"So, do I need to sign it?"

Chaochao leaned closer and watched her brother register with longing eyes.

The security guard glanced at the little girl peeking out from behind the table. She was as white and adorable as a porcelain doll, like one of the celebrity children on TV. The guard's rough voice unconsciously tightened, "No need, no need. Children under five are not registered."

Upon hearing this, the little dumpling let out a slightly regretful "ah".

But after Pei Yushen finished signing his name, he didn't stop the black ink flowing from his pen and drew a cute little sun without pausing.

The smooth strokes of the brush instantly warmed the cold white paper and black characters.

The boy put down his pen after finishing all of this.

"It's signed."

I signed your name on it too.

Originally a little disappointed and focused on waiting for Pei Yushen's autograph, Chaochao had already opened her almond-shaped eyes wide in a daze when the boy smoothly sketched the little sun. Her suddenly bright and sparkling gaze almost burned through the paper.

"hey-hey--"

The little dumpling, whose wish had been fulfilled, grinned happily.

The system couldn't help but marvel at Pei Yu's profound astonishment.

Wow, you've got a knack for charming kids.

I really underestimated you before.

You're no longer the stubborn, unyielding block of wood you once were.

Before leaving the post, Chaochao took a few photos of her smartwatch and the registration form to preserve the precious record of Yushen signing it for her.

The security guard watched the boy and girl in the wheelchair gradually disappear into the distance, feeling a sense of loss and regret.

He remembered Pei Yushen.

In the past, this boy would often stay in the laboratory until very late before going home, and on his night shifts, he could always hear the boy, dressed in a clean and crisp school uniform, knocking on the window and calling him to open the door.

A student with good grades, high self-discipline, good looks, and good manners.

It was just fate playing tricks on us; that thing happened later.

But looking at him today, the security guard had a vague feeling that he was seeing the shadow of that young boy from before...

But then again, the girl sitting so close to Pei seems to have a very good relationship with him. Who is she?
