Yuzuru understood immediately and turned to walk towards the "flower ladder" woven from vines and flowers.

The flower-patterned staircase carried him lightly up to the seventh floor.

The laboratory's metal door slid open silently.

The scene inside was completely different from the cozy atmosphere downstairs, filled with the coldness of futuristic technology. Various sophisticated instruments emitted a low hum, and complex data streams flowed across the screens.

In the center of the laboratory.

A tall, slender figure stood with her back to the door, intently observing a trembling little monster inside the isolation pod.

She wore a slightly loose white lab coat, with the sleeves casually rolled up to her elbows, revealing her beautifully shaped, fair-skinned forearms. She had short, slightly wavy brown hair, a tall and straight posture, and an aura of cool sophistication. Even just her back view exuded a powerful presence.

It's Ai-chan who used the Time Bag to transform back into Shiho Miyano's form.

Clearly, for certain "important moments," she prefers to face things as she truly is.

At this moment, she held an electronic recording tablet, her cool voice echoing in the laboratory: "...Resistance test, seventh sequence, magic tolerance threshold still 17.8% below the standard value, demonic energy activity significantly suppressed...failure. Record time..."

Inside the isolation chamber, the little monster that looked like a dandelion spirit huddled in fear, wishing it could turn into a wisp of air. Its eyes were filled with terror and despair as it looked at the mad scientist girl in front of it.

In this household, which monster doesn't know that the one person you absolutely must not mess with is Princess Ai, who has a cold and beautiful appearance but whose experimental methods are "inhumane"?

Falling into her hands is worse than being taken by a master!

The arrival of Yuzuru Nanami gave the little monster a savior.

Taking advantage of the moment when the mad scientist was distracted, it turned into a wisp of smoke in a flash and slipped away through the gap in the pressure relief valve at the fastest speed it had ever traveled, disappearing without a trace in an instant.

Shiho Miyano: "..."

Holding up the whiteboard, she stared at the empty isolation pod, remained silent for two seconds, then slowly turned around, her icy blue eyes glaring at Yuzuru with a hint of annoyance: "Look, they ran away. How are you planning to compensate us?"

Seeing her feigned seriousness, which was actually a bit of a letdown, Yu Sheng Nan couldn't help but laugh out loud. He stepped forward and naturally put his arm around her waist.

"How about I compensate you with myself? You can 'study' me however you like, whether it's biopsy observation or physiological experiments, I guarantee my cooperation and the data will be absolutely true and reliable."

Shiho was pulled into his arms and struggled symbolically for a moment.

She then relaxed, habitually finding a comfortable spot to lean against him, and gave a soft hum, her tone still carrying a hint of disdain: "...Who wants to study you? You're thick-skinned, your data is abnormal, your energy fluctuations are unstable, and there are too many interfering factors. You have absolutely no scientific reference value."

A typical example of lamentation-style denial.

"My bad, my bad. Next time I will knock on the door and wait until our Shiho-sama finishes her experiment before coming in."

Yu Shengnan readily apologized, gently twirling a strand of her brown hair with his fingers. He lowered his head and sniffed her hair; it was the familiar faint scent of disinfectant mixed with her unique cool fragrance.

"However, compared to the apology gift, it seems there's something more important I haven't received today."

He was implying something.

His gaze swept over the spotless lab bench next to him.

The proud young girl's body stiffened almost imperceptibly.

She then pushed him away, feigning composure, and turned to the data terminal next to her, pretending to be busy retrieving information from the screen: "...What is this? Besides being Valentine's Day, which is being hyped up by capital and commerce, does today have any special scientific significance? I didn't pay attention."

"Oh? No?"

Yuzuru followed her, wrapped his arms around her from behind, rested his chin on her slender shoulder, and looked at the scrolling gene sequence diagram on the screen, which he couldn't understand at all.

"I don't have time to make those childish and time-wasting desserts."

"Really?"

Yuzuru's voice was tinged with laughter, and his arms tightened a little. "But I think I can smell it... In the air, besides the smell of chemical reagents, there's also a little bit of... the unique caramel aroma of heated cocoa butter and sugar?"

Shiho Miyano's fingers paused as she typed on the keyboard.

She took a deep breath, turned around abruptly, and almost bumped into Yuzuru's chin.

Her icy blue eyes stared directly at him, carrying a hint of embarrassment and resignation at being exposed: "Yes, I did it, so what? It was just because I saw that my sisters had all done it, and the lab happened to have some high-purity cocoa butter and glycosides left over from experiments, so I didn't want to waste the resources."

"It wasn't made especially for an idiot like you!"

As she spoke, as if in a fit of pique, she pulled a box from the large pocket of her lab coat and shoved it directly into Yuzuru Nan's arms.

"Here you go! Take it and get out of here, don't bother my work!"

The box is made of simple transparent acrylic material, without any fancy packaging, so you can clearly see the contents inside.

However, it is precisely this extremely simple, even somewhat "laboratory-style" packaging that makes the chocolate artwork inside all the more stunning and eye-catching, creating a strong contrast.

That wasn't an ordinary heart or square shape.

Three chocolates of different colors were carefully carved, polished, and pieced together to form a lifelike miniature sculpture.

At the highest point in the middle is a lifelike image of a young man with smiling eyes and a languid posture, capturing even the nonchalant charm of Yuzuru Hanyu.

A girl was nestled on each of the boy's left and right sides.

On the right is Akemi, dressed in a maid outfit with a gentle and sweet smile, while on the left is Shiho, wearing a white coat, looking to the side with a slightly awkward expression, but secretly tugging at the boy's clothes with one hand.
