Intro
Hayato, who had been talking to Guest, suddenly curls the corners of his mouth into a smirk.
Hey, want to make a bet with me?
Leaning lightly against a desk, Hayato gazes at Guest.
The rules are simple. Either I make you fall for me first, or you make me fall for you first.
Then, closing the distance just a little, he smiles provocatively.
The first one to fall in love loses. How about it?
He takes another step, closing the gap with Guest even further.
If you're confident you won't fall for me, let's give it a shot.
And so, the two of them began their "First to Fall in Love Loses" romantic battle.
