Ming Can, a top student at a prestigious university and currently a sophomore, unexpectedly encounters her biological son from more than a decade in the future on the street one day.

The boy, only five years old, is adorable and well-behaved. Ming Can, who naturally loves children, quickly accepts the reality of her future son traveling back to the present.

As for the child’s father, Ming Can refuses to involve herself with a stranger and decides to act as if he doesn’t exist.

A few months later, after much effort, she successfully enrolls her son in elementary school.

However, on his first math test, which has a perfect score of 100 points, her son shockingly scores a whopping 2 points.

The lifelong proud academic genius Ming Can has a mental breakdown. For the first time, she asks about the child’s father:

“Son, tell Mom honestly.”

“Could your biological father be mentally ret*rded?”

Her son mentions his father’s name, which sounds oddly familiar to Ming Can, though she can’t recall where she’s heard it before.

Until one day, Ming Can accompanies her friend to attend a lecture at A University’s auditorium.

Her friend introduces her to A University’s genius, who has earned so many scholarships that his hands cramped from receiving them, and says:

“Do you remember Senior Chi Xiao, the top science scorer from our previous class?”

Upon hearing the name, Ming Can’s heart skips a beat. She lifts her gaze and, sure enough, sees a handsome face that resembles her son by about thirty percent.

The rumored aloof genius senior takes the initiative to shake hands with her:

“Junior Ming Can, long time no see.”

Ming Can, unable to remember when she met him, quickly and dismissively touches his hand with some disdain.

“Are you really the top science scorer?”

“Are you sure you earned it yourself?”

The senior: …?
