He Li and Gao Yiyang have known each other since birth.
After years apart, they bump into each other at a dinner attended by their parents.
Gao Yiyang, who'd always thought He Li was a new classmate, awkwardly says, "You've changed so much!"
He Li: "You just didn't recognize me? You even forgot my name!"
Gao Yiyang: "Then do you remember me?"
He Li: "Uh... not exactly."
After another long separation, they meet again.
He Li: "You didn't recognize me again."
Gao Yiyang: "You're the one who forgot me again, you little punk."
College campus + mutual firsts + happy ending
