Xia Xi bought an ice cream at the small supermarket next to the cafeteria. Not afraid of the sun, she ate it while walking slowly on the road from the cafeteria to the dormitory.

When she returned to the dormitory and had just finished her ice cream, she heard voices from inside. It was her roommates who had arrived.

"I was just wondering who came so early and the bed was already made. It turned out to be our beautiful Xia Xi. I haven't seen you for a whole holiday. I missed you so much." Zhao Lei blinked, holding a bottle of iced mineral water in her hand. She took a sip, and the broken ice inside hit the wall of the bottle, making a rustling sound.

Xia Xi smiled and asked, "Have you had lunch?"

Zhao Lei said: "I ate it, but they didn't."

Wu Qinglu and Wang Qiuyu were making their beds. Upon hearing this, they looked down from the upper bunk. One said she had no appetite, and the other said she had bought some bread.

They used to live in the same dormitory and were familiar with each other, unlike the strangeness and politeness of freshmen. Xia Xi nodded, put on her pajamas, went to the bathroom to take a shower, and lay down on the bed for a nap.

Xia Xi woke up at 1:30, feeling a bit hot. She fanned herself with a magazine beside her pillow. Holding her phone in one hand, she sent a private message to Liang Yuan: "Want to go swimming? I checked. There's a huge swimming pool near the school. It's not far from your school."

Xia Xi learned to swim this summer vacation and was very excited about it. She felt uncomfortable if she didn't swim a few laps every day.

Liang Yuan: "I didn't sleep at noon, and now I'm too sleepy to swim."

Xia Xi didn't force her: "Okay, I'll go by myself."

Xia Xi is a person of action. She will leave as soon as she says she will. She threw down the magazine in her hand, supported herself on the bed and climbed up. Seeing that everyone else was taking a nap, she got out of bed quietly, found her sports bag, stuffed her swimsuit, goggles, swimming cap, towel and other things into it, put on her sneakers and left.

After taking a taxi to the Blue Whale Swimming Pool, Xia Xi first went to the front desk to apply for a card. She would probably visit the pool frequently in the future, so it would be more convenient to apply for a card.

The receptionist asked her to wait, dialed the internal line of the landline, and called someone to come and greet her.

It was noon and the weather was very busy. The person who was called over looked tired, but when he saw Xia Xi, his eyes lit up and he suddenly became extremely enthusiastic. He asked her if she wanted to buy lessons or make an appointment with a coach, and he could recommend the best coach for her.

Xia Xi refused, saying that he could swim and just wanted to use the swimming pool.

After sending the waiter away, Xia Xi went to the locker room, changed into her swimsuit, tied her long hair up, put on a swimming cap and goggles, and headed for the swimming pool. After doing two sets of warm-up exercises on the shore, she put her hands together and stretched them forward, jumped into the pool, and instantly transformed into a mermaid, swimming two laps in the blue water.

At this time, there was no one else in the swimming pool except her. It was a rare moment of peace and quiet. She greedily swam back and forth again.

When she got ashore, Xia Xi touched her neck and found that the necklace she had been wearing was gone. It was the one her sister had given her last week and she loved it. Without thinking, Xia Xi jumped into the swimming pool and must have dropped it in. She remembered clearly that the necklace was still there when she changed clothes because it got caught in her hair.

Xia Xi searched at the bottom of the pool for a long time and finally found the sparkling chain in the corner near the pool wall. Her face lit up with joy, and she swam over with her arms, squatted at the bottom of the pool, picked up the necklace, and held it tightly in her hands.

Just as she was about to float up, her calf suddenly cramped, probably from being in the cold water for too long. Even in the middle of summer, the human body couldn't handle it.

Xia Xi felt that the situation was not good and was a little panicked. She tried to stay calm and slid up despite the discomfort. However, her legs had no strength at all. The more she struggled, the faster she lost her strength. Finally, she couldn't hold her breath anymore and choked on two mouthfuls of water, which made her lungs feel very uncomfortable.

She wanted to call for help, but no sound came out when she opened her mouth.

When she was in despair, she suddenly heard a "splash" sound in her ears. Someone jumped into the swimming pool and swam towards her.

In a moment, strong arms lifted her body from behind. Instinctively, she grabbed the other person's arm with all her strength as if it were a life-saving straw, turned her body over, and used her hands and feet to wrap around the man like an octopus.

She clearly felt the body stiffen for a moment, and then it dragged her, the burden, with one hand and swam towards the shore.

After a long while, Xia Xi gradually recovered, coughed a few times, opened her water-blocked eyes, and saw clearly the person who saved her.

He didn't look like a coach. He was young and incredibly handsome, his pale complexion looking clear and clean from the water droplets. He wore a black raglan-sleeved swimsuit and two-layered trunks: a tight inner layer and a sweatpants-style outer layer, unlike the awkward, ordinary men's swim trunks. He had removed his swim cap, his short, fluffy hair making him look even younger.

Xia Xi was stunned.

"Um..." Xia Xi coughed again, her throat a little uncomfortable, and her voice was hoarse. "Thank you, what's your name, which school are you from, or leave your contact information, I'll treat you later..."

Before she could even utter the word "eat", the man saw that nothing was wrong with her, so he got up and left without swimming.

Xia Xi touched her face and for the first time doubted her appearance. Was she so unattractive?
