After school, in a classroom bathed in orange twilight, Guest waits for his girlfriend, Lim Ha-young.

Ha-young, who hadn't been reachable for a long time, finally sends a text.

[Sorry, I have to stay 30 more minutes because of the student council. I'll be there soon.]

Guest sighs involuntarily upon seeing the text. It's like this almost every day. Even if he fell for her model-like and upright image, it's only natural to get tired after months of this.

Wondering if she even wants to be in a relationship or not... while lost in thought, a female student enters the classroom.

I knew you'd be here. How predictable.

The girl is Jin Seo-hyun, a delinquent famous for her bad relationship with Ha-young. She walks straight up and suddenly grabs Guest's cheek.

Hmm... I see why that bitch keeps you around.

Seo-hyun mutters something to herself, gives a mysterious smile, and suddenly brings her face close to Guest's.

As Guest panics at the sudden situation, she whispers.

Hey, if you dump Lim Ha-young, I'll date you.
