The baby slapped me, and I said, "Sit on my lap and slap me."

After an unknown amount of time, Wen Yu finally stopped, pressing his forehead against Su Qingyao's and breathing heavily.

His eyes held lingering emotions and an intense, overwhelming sense of satisfaction.

"This letter," he picked up the letter, his fingertips lightly tracing the handwriting, "I want to frame it and hang it above my bed."

"No way!" Su Qingyao hurriedly tried to snatch it back, "It's too embarrassing..."

Wen Yu easily dodged, raised the letter high, and kept his other hand firmly around her.

"This is my first love letter to me, my baby, so of course I have to look at it every day."

"Wenyu!"

"unless……"

He suddenly leaned closer, a sly glint in his eyes, "Baby, promise me you'll write me a letter every year on my birthday."

Su Qingyao glared at him, "How can you say that..."

"Then frame it." Wen Yu pretended to put the letter into his pocket.

"Wait!" Su Qingyao grabbed his sleeve, her face flushed red.

"...I promise you."

Wen Yu smiled triumphantly, then pulled her back into his arms, gently rubbing his chin against the top of her head.

"Baby," his voice softened, "I'm so happy."

Su Qingyao leaned against his chest, listening to his rapid and powerful heartbeat gradually regain its composure, and the corners of her mouth unconsciously turned up slightly.

Wen Yu suddenly remembered something, lowered his head and kissed her head heavily.

"Baby," he said, his voice still hoarse with satisfaction.

"Of the locations you mentioned before... the study is now a complete success."

He ran his fingers through her hair, his tone becoming seductive, "Where would you like to go next?"

Su Qingyao's body was still sore and weak. Upon hearing this, she glared at him fiercely and reached out to pinch his cheek.

I kneaded it several times without any restraint before I felt a little better.

Wen Yu smiled and let her do as she pleased, his gaze lingering on her flushed cheeks and moist eyes.

Her pouty yet delicate appearance made his heart flutter, and he couldn't help but lean in again, planting several light kisses on her cheeks and lips.

"Baby," he hugged her tighter, his voice deep and solemn, "I love you so much."

"I really...love you so much."

Thank you for being with me.

He gently buried his face in the crook of her neck, and when he spoke again, his voice trembled slightly with disbelief at his own happiness.

"Thank you……"

"You can like me too."

As the moonlight deepened outside the window, the warm yellow lamplight gently cast the silhouettes of the two people nestled together onto the wall, creating a warm and inviting scene.

After a long while, Wen Yu asked softly, "Are you hungry? I noticed you didn't eat much earlier."

"A little..."

"What do you want to eat? Your husband will make it for you."

Su Qingyao gave a lazy hum, deliberately making things difficult, "A Manchu Han Imperial Feast."

Wen Yu raised an eyebrow and nodded in approval. "Okay, I'll have someone send the ingredients over."

"Just kidding," she muttered, reaching out to poke his chest.

"I'm exhausted... carry me to take a bath."

Wen Yu chuckled and pinched the tip of her nose, "Little spoiled brat."

He then gently picked her up and carried her towards the bathroom.

He carefully placed her into the bathtub filled with hot water, tested the temperature, and said, "Baby, soak for a while first, I'll call you when your midnight snack is ready."

Su Qingyao, immersed in the warm water, watched his back as he turned and left. She couldn't help but secretly raise her fist and make a "I'll punch you" gesture towards the air.

Unexpectedly, Wen Yu seemed to sense something and suddenly turned around.

She immediately lowered her hand, looked innocently at the ceiling, and pretended nothing had happened.

Wen Yu had already caught this little movement clearly in his peripheral vision, and his heart felt as if it had been tickled by a feather, making him feel completely soft.

He suppressed a smile and closed the bathroom door for her.

Walking back to his study, his gaze fell on a slightly wrinkled letter on his desk.

The smile in his eyes spread silently, gentler than the moonlight outside the window.

This is the first love letter his baby wrote to him.

There will be a second, a third...

Countless letters.

They have a long and bright future ahead of them.

He picked up the laminator next to him and carefully sealed the letter. Then he opened the built-in safe in the wall and placed it inside with great care.

The metal latch clicked softly when the box door was closed.

The overwhelming love and promises of this moment are locked away for the years to come.

-

In September, Su Qingyao and Wen Yu both entered their second year of university.

The physics curriculum suddenly became more advanced, and experiments and research projects followed one after another.

Su Qingyao quickly became engrossed in it; the microscopic world under the microscope, the rigorous logic of the formula derivation, and the repeated verification of experimental data all fascinated her.

However, this significantly reduced the time she could spend dating Wen Yu.

Several times, Wen Yu waited for her at the library until closing time, only to see her rushing over with a thick stack of materials, her eyes sparkling as she shared what she had learned that day with him.

Wen Yu felt sorry for her and gently pulled her into his arms, massaging her temples.

He didn't show it on his face, but he was filled with sorrow in his heart.

Physics, his lifelong enemy.

It's one thing to not understand when you're in school, but now you're even taking up your wife's time when you're on dates!

They only ate together four times this week, postponed the movie screenings twice, and even the promised three times a week were only completed twice.

But every time I see the light in her eyes when she talks about physics, those resentments turn into a deeper tenderness.

Wenyu likes the baby's appearance.

He wanted to see her grow stronger, to see her shining brightly as she pursued her ideals, and to see her become someone he could rely on with her own brilliance.

His love is the wind that lifts you up, the cloud that protects you.

He would never become like Wen Tianyao, that pathetic and pitiful person.

So Wen Yu quietly tried to find a way to make Su Qingyao's path smoother.

The Physics Department at Kyoto University has received several donations with specific targets.

The latest model of scanning tunneling microscope, high-precision laser interferometer, a complete quantum computing simulation platform...

These are all cutting-edge devices that are extremely difficult for domestic laboratories to obtain.

Su Qingyao soon discovered that many instruments she had only seen in literature were appearing in the school's laboratories.

Her teachers and senior students also paid more attention to and provided guidance on her research. On several occasions, the dean would even ask her a few questions about her progress when he passed by her lab bench.

She had a vague idea in her mind.

It was late at night when she came out of the lab that day. Wen Yu was waiting downstairs, holding a cup of hot milk.

The autumn night was slightly chilly, so he draped his coat over her shoulders and listened as she excitedly recounted the phenomena she had observed that day using the new equipment.

As they walked, Su Qingyao suddenly stopped and turned to look at him under the streetlight.

"Wenyu, those new instruments in the lab..."

"Hmm?" Wen Yu's expression remained unchanged, only his grip on her hand tightened slightly. "Is it easy for the baby to use?"

The answer is self-evident.

Su Qingyao's eyes welled up with tears, and she buried her face in his chest.

"I will work harder." Her voice was muffled, but firm.

"I know." Wen Yu kissed the top of her head.

"My baby has always been amazing."

Touched, Su Qingyao became even more engrossed in the moment, not wanting to let Wen Yu down.

A few days later, Wen Yu was slumped in the sofa of Junyu's private room, the metal lighter clicking and turning between his fingers, making a monotonous, crisp sound.

The warm yellow light illuminated half of his face, but a thick, unyielding melancholy hung between his brows.

Jiang Shubai leaned closer, his expression inquisitive and playful.

"Didn't we just donate several batches of top-of-the-line equipment to the physics department? Qingyao must be overjoyed, right? Why are you here alone?"
