Socially anxious top student Qi Leyang likes to keep to himself.
One day, he accidentally overhears the secret that Jiang Yicheng, the school's celebrity "Prince of the Campus," has fallen on hard times and is buried in debt. He even witnesses Jiang Yicheng in a humiliating state, with snot and tears streaming down his face.
At first, Jiang Yicheng mistakenly thinks Qi Leyang leaked the secret. But when they confront each other, he discovers that Qi has no friends and is an "oddity" who can absolutely keep his mouth shut.
When his former buddies distance themselves from him and mock him, Jiang Yicheng latches onto Qi Leyang, asking him to eat with him and teach him "how to live on your own at school."
"Could you eat with me tomorrow?"
"Too much trouble!"
"...Then just walk me to the cafeteria entrance."
"Three seats apart."
"Huh?"
"Sit a little farther away from me, at least three seats apart."
"Deal!"
And so the two begin a chaotic school life as lunch buddies. Little by little, Qi Leyang realizes that Jiang Yicheng is a lot more twisted than he ever imagined...
