"My name is Kang Juyeong, from the English Literature Department..."

Juyeong, an English major, attends the freshman orientation and accidentally overhears a rumor about Choi Hyun—

"Choi Hyun from the Physical Education Department accepts confessions easily, even from strangers."

Amid the rowdy atmosphere of a drunken party, his friends dare someone to confess to Hyun for a 100,000-won bet. Uncomfortable, Juyeong decides to leave... only to bump into Choi Hyun himself, who’s just turned someone down.

"Go out with me too!"

The truth is, Juyeong has been secretly in love with him since high school. Without thinking, he grabs Hyun’s wrist to stop him from walking away and blurts out a rushed confession.

And just like that, their relationship begins that very night—starting from "Day 1." But how long can Juyeong last with the man he’s loved in silence for years?
