Chapter 52.52 The Swaying Green Light: The Personal Trainer and the Jealous One

On Monday afternoon, New York City was still so hot that there was no hint of the cool breeze of late summer. Liang Siyu drove towards Long Island.

Before leaving, he repeatedly confirmed that Xu Aida was okay with Long Island and assured them that they would stay at home and not go out.

She asked in surprise, "Aren't you supposed to be practicing capsizing? Aren't you going to the rowing club?"

He shook his head: "I can practice at Granny's pool. I called yesterday and had the club bring my single-person boat back."

Grandmother Jenny Viv has always maintained the habit of swimming. There is a 20-meter-long heated pool in her backyard, which is perfect for practicing capsizing.

Xu Aida then remembered Granny Vivi's swimming pool, which was a very comfortable heated pool with a glass wall facing the lawn and garden, offering different views in each season.

Moreover, I don't know what design they did, but the humidity control is exceptionally good; there's no stuffy, humid feeling.

They arrived at lunchtime, and Mrs. Anderson, who had cared for Jenny Viv for many years, was waiting for them at the door, greeting them happily.

She said with a smile, "Ned, your little guy has been delivered. Jenny ordered pho and mango shrimp rolls for lunch today."

Liang Siyu also asked with a smile, "Do you also have double condensed milk coffee?" Every time her grandmother ate Vietnamese food, the thing she cared about most was this super sweet coffee.

They had a simple and refreshing lunch together. Before going back to her room to rest, Jenny Viv winked at Xu Aida: "I picked out a few swimsuits for you. You young ladies should enjoy the sun."

They returned to the bedroom and looked at the colorful mess on the bed. Liang Siyu shook his head helplessly: "Granny is really..." He couldn't find the right words, so he looked at her with a hint of apology.

She smiled slightly, indicating that she didn't mind, and then picked up a green swimsuit with purple floral prints to look at it: "Oh, this color scheme is very unique."

“The color suits you very well.” He cleared his throat, his eyelids slightly lowered. “However, let’s take a short nap first. After the boat capsizes, practicing getting back on will take some stamina.”

As she lay down, she instinctively leaned into his arms, but he flinched away, his breathing heavy.

She paused for a moment, then chuckled, "Ned, it's just a swimsuit. I haven't even put it on yet."

"Don't wear it in the afternoon either," he took a deep breath, "that's not suitable for exercise."

The only thing he prepared for her was the simplest black training outfit: crew neck, short sleeves, and boxer shorts, avoiding any visual distractions.

The afternoon sunlight was gentle like scattered gold. Hsu Ai-ta sat on a silver-white boat, floating in the middle of the azure pool.

Liang Siyu stood beside him and lowered the oars to be parallel to the water surface to prevent them from hitting the bottom if the boat capsized.

To learn standard racing single-person boating, the first step is to learn how to save yourself after capsizing.

Today, Xu Aida needs to learn how to actively capsize the boat to become proficient in this process.

Liang Siyu counted on his fingers: "First, hold your breath immediately; second, unfasten the buckles on your shoes; third, swim out from the stern of the boat, understand?"

“No problem!” Xu Aida sat in the boat, eager to try. “Move aside, let me give it a shot.”

He added with a final word of concern, "After you roll over, you'll feel a momentary loss of weight. Don't panic, and make sure you hold your breath. Even if you forget what to do next, it's okay. I'll come find you right away. Don't be afraid."

"I know, I know." She waved her hand.

This is an indoor pool, not an open water pool, so what's there to be afraid of? Holding her breath for a few seconds is nothing; she swims all year round, it's incredibly easy for her.

He pursed his lips, paddled a couple of times, and had just returned to the edge of the pool when, before he could even give the command, she had already tilted to the side. With a snap, the small boat lost its balance and flipped over, the oars spinning in the air.

He wanted to curse, but he couldn't care less about anything else, so he pushed off the pool wall and swam back.

Across the clear pool water, she gracefully and nimbly emerged from the boat, flashing him a "Yeah!" before surfacing.

"Ada, you promised to only capsize the boat when you give me the command!"

She laughed, "Honey, you're too nervous. I'm just trying to ease your anxiety."

He emphasized, "In the water, you must follow instructions; safety comes first!"

She flung her arm and threw herself into his arms: "Okay, okay, I was wrong. I'll definitely listen to commands next time."

The gentle touch of the water on her skin made him catch his breath; her ivory-like arms appeared even softer against the black swimsuit.

He grabbed her wrist: "Okay, come on, let's see how to put the racing boat in place."

He swam to the stern of the boat, first adjusted the oars slightly, then lifted the stern, grabbed the gunwale and turned, and the boat flipped back to right itself.

“Carbon fiber boats are very light and have the buoyancy of water, so you should be able to do it.”

This step wasn't difficult, and Hsu Ai-ta easily followed along. The next step was the most strenuous: boarding the boat.

He explained the key points of the movement in detail. The most basic way is to first climb onto the boat on your belly like a seal, then turn around and return to a sitting position, and then put your legs onto the boat.

He slowed down his movements and demonstrated step by step, then jumped down: "Try getting out of the water and pushing the boat out by yourself first. Use your hands to support the paddle and the boat to gain leverage, and use your legs to kick the water forcefully. Find the feeling of jumping out of the water."

She nodded, took a deep breath, and tried her best to push, but she didn't get high enough out of the water and almost capsized the boat again.

"Ah!" she exclaimed, quickly sliding down the slope. He swiftly reached out and caught her in his arms.

She gently nudged him with her elbow to indicate that she was alright, but he wouldn't let go.

"Do you want me to help you get a feel for it?" He wrapped his arms around her waist, asking for her opinion, but his arms had already lifted her up, and she was instantly out of the water.

"Look, you must press your lower abdomen against the boat. This is your body's center of gravity. This way, the weight is even on both sides, and the boat can be balanced."

Hmph, who doesn't know the principles of physics? She bit her lower lip lightly. The problem is, it takes some explosive power to completely leap out of the water with her upper body.

She tried several more times, but each time she was just a step short.

He pulled her close: "Come on, let's go ashore and rest for a bit, then we'll try again later."

On her last attempt, she was clearly exhausted, and her height above the water dropped considerably.

Xu Aida was a little out of breath. She had never exerted herself this much in her previous life. She succeeded on her third try.

Even though it was the same movement, and she tried her best to tighten her core and tread water quickly, she still felt weak and powerless.

After getting ashore, he first wrapped her in a towel, then dared not look at her again. But without visual stimulation, the sound of her slightly panting breaths added an indescribable allure.

He clenched his fist, calmed himself down, and brought over a small glass of grape juice: "Try this grape juice, it's from the neighbor's garden."

She took small sips; it had a unique fruity aroma, somewhat similar to what she had at the Napa Valley winery.

She asked, "Is this grape juice from the winery?"

"Yes, they have a small vineyard, and they make their own wine every year, and also make some grape juice for relatives and friends."

She smiled briefly, then lowered her head again, still feeling somewhat down.

He rubbed her shoulders and comforted her, "Next time I'll press the other side first, and then you can try."

Although this is not usually done in indoor still water, in open water, when he first started practicing getting on the boat, the coach would use the oar to help him press down, which could better maintain the balance of the boat and reduce the difficulty of getting on.

She turned her face away and muttered softly, "What difficulty could there be? I'll definitely make it up."

He patted her little bun: "Ada, our coach always says, never underestimate Baby Steps."

Rowing is a sport that relies heavily on muscle memory and attention to detail. Small improvements in the rhythm of the strokes may not be noticeable in the short term, but repeated thousands of times, the difference will become apparent.

She gently bit her lip: "Okay, I'll try it as you say."

I have to admit, there's a lot of truth to that. She really shouldn't be in such a rush right now. This girl seems to always manage to spout some philosophical insights while rowing.

Huh? Why is her hair falling down? She looked up.

He awkwardly withdrew his hand: "I... I don't know what happened either."

Her hair was as soft as water, and he couldn't resist touching it and playing with it. For some reason, he ended up making her hair all messy.

She chuckled and tied it up again.

This time, he helped to give the boat a handy, and she succeeded on her first try.

Seeing that her mood and physical strength were still good, Liang Siyu continued to maintain interval training, practicing for 15-20 minutes, resting for 5-10 minutes, and then continuing.

She was still unsteady when she jumped out of the water, but she quickly mastered adjusting her posture and flipping back onto her seat on the boat, her movements agile and graceful.

He smiled and praised her, "You have great balance. Don't worry, after a while, I'll do some weight training with you, and you'll be fine soon."

Her cheeks were flushed with the joy of exercise: "That's right, I'm pretty good at surfing and paddleboarding."

He gently placed his hand on her waist: "Come on, get down, let's go back and rest."

They each took a shower in the changing room, wrapped themselves in bathrobes, and went back to their rooms. As soon as Liang Siyu closed the door, he turned around and froze.

She wore a green bikini with purple flowers, but what was more striking than the vibrant print was the soft glow of her skin and her long, satin-like hair.

He kissed her passionately; the sweet and sour taste of grapes still lingered on her lips, almost causing him to lose all self-control.

Until the very last moment, he struggled to rush to the bathroom, where cold water was poured over his head.

When he came out, she was sitting on the headboard, holding a book, without even glancing at him.

He sat at the foot of the bed: "We still have to go downstairs for dinner in a little while."

Since she's coming over, her grandmother will definitely be preparing a full-course meal tonight, which will take at least two hours.

Besides, she just had some intense exercise, so it's best for her to rest quietly tonight and not do anything.

A pillow flew towards him. He pretended to fall backward off the bed, and she jumped down in fright.

He got up and hugged her. She angrily punched him and complained, "You scared my heart."

His expression changed drastically. He quickly carried her back to bed and pressed his hand against her neck to feel her heart rate.

She couldn't help but laugh, her mood brightening from cloudy to sunny.

On Tuesday, when returning to the city, Xu Aida happily turned on Spotify, connected to the car's Bluetooth, and selected Perfume's "Spending all my time".

Liang Siyu raised an eyebrow: "What's this?" Why did she suddenly start listening to electronic music?

"To give back to my rowing coach, I'll give you some multicultural nourishment."

He wasn't a big fan of electronic music, but listening to these lyrics made him feel wonderful, and he was willing to spend all his time with her.

Unfortunately, by evening, Liang Siyu hadn't enjoyed any pleasant moments; instead, she felt a tightness in her chest.

He was filled with regret; he shouldn't have picked out that green dress and encouraged her to try it on.

That touch of green, like the fluorescent glow on a lake on a summer night, flowed over her. At this academic banquet, anyone with eyes could see her beauty.

Looking into the man's deep eyes, he wished he could pull her away immediately.

But he couldn't. He couldn't even put his arm around her waist to suggest their relationship; it would be too disrespectful to her in this situation.

Alvin, a doctoral student in the mathematics department at New York University, smiles.

He had initially thought it was going to be a boring dinner, but now things were getting interesting.

"You want to use adversarial networks (GANS) to generate muscle electrical signal data? Wow, that's a bold idea."

Xu Aida shrugged: "No, that's the normal way to think about it. GANS is suitable for this problem."

“This is the first time I’ve heard of someone trying to use GANS to generate meaningful time series data. You know, everyone else is trying to generate…” Alvin looked at her and suddenly paused.

"Pictures of kittens".

Xu Aida and he spoke in unison, then the two looked at each other and smiled.

In the first year after GANS was created, most researchers in the field of visual computing tried to use it to generate animal images because they were easily distinguishable by the naked eye, and the training effect of the discriminator was indisputable.

A second later, Liang Siyu forced a smile. He couldn't understand the cryptic conversation between the two, so he could only feign agreement. In the past, these moments clearly belonged to him and her.

Xu Aida even lowered his voice a little: "I heard you're researching a key issue?"

Liang Siyu felt even more jealous. What man wouldn't be captivated by her inquisitive yet curious expression?

Sure enough, the man couldn't resist her little trick and immediately replied, "I just wanted to better explain the reason for gradient vanishing from a theoretical perspective. I just had a little idea."

“Explanation is the beginning of a solution.” Xu Aida smiled slightly. “You also think that the JS divergence is not quite reasonable, right?”

Alvin's interest was fully piqued: "Yes, we're trying to prove..."

As Liang Siyu watched the two chatting happily, their heads getting closer and closer, he couldn't help but tense his arms.

She was having a lively conversation with another man, a math PhD student she had known for less than half an hour.

And he, her collaborator and boyfriend, couldn't get a word in edgewise.

He had opposed the algorithm last week and was of no help when she encountered technical difficulties.

They took out their phones and followed each other on social media. Alvin even said that once he finished the first draft of the paper, he would like to invite her to read it.

“Check if there are any problems.” Alvin’s gaze was focused. “I believe there are very few people in all of New York who understand GANS as well as you do.”

Xu Aida blinked: "How can you be sure I didn't finish first?"

Alvin was stunned, but a hint of a smile, rather than displeasure, then appeared in his eyes.

“Just kidding, don’t mind it,” Xu Aida quickly added. “I want to be the first person to cite your paper. I’m more interested in practical engineering applications. Leave the rigorous derivations to you mathematicians.”

This is a light compliment, but it's not without its sincerity.

After ending her conversation with Alvin, she turned to look at Liang Siyu, who was gazing at her tenderly, his gaze focused. She looked out the window and gave him a knowing look.

The two of them slipped away to a corner, and she stretched lazily, feeling absolutely ecstatic.

She neither wanted to plagiarize others' work nor wanted her research progress to be delayed.

What a coincidence! I ran into Alvin today, a GANs guru. His paper next February will offer a theoretical explanation of the gradient problem, and the year after that he will publish a specific solution.

She naturally thought that if she gave him a slight hint so that he could finish the relevant paper ahead of time, wouldn't the problem be solved?

So she took the initiative to greet him and discuss the research, and now it seems that everything is going smoothly.

“Ned, this is a really nice evening,” she remarked with a smile.

"Oh, of course," Liang Siyu replied softly. Seeing that no one was paying attention, he took her hand and gently stroked it.

He tried hard to convince himself that this was just an academic exchange. But didn't he and she also start with academic topics? It was all so similar to the atmosphere when they first met.

Stop, stop! Liang Siyu told herself to stop this far-fetched association.

Ada isn't the kind of girl who falls in love with every guy she meets; he's just worrying unnecessarily.
