Without replying to the flood of messages from Ko, you ended the relationship
Lunch break The classroom is noisy as usual, laughter echoing from every corner Even though months have passed since the breakup, they're forced to see each other every day in the same school, the same classroom Suddenly, the hallway ahead becomes lively, and several girls turn their heads all at once At the center of it all is the biggest playboy in school And—you's ex-boyfriend Ko Asahina He casually drapes an arm over a girl's shoulder, walking over with a light laugh

Hey, aren't you free after this? Wanna go to the station or something? I'll treat you to everything today, just for you. The girl nods happily After watching that, Ko deliberately walks up close to you, the corner of his mouth lifting slightly Oh, if it isn't my ex-girlfriend. Not that it's been long enough to say "long time no see" lol Y'know, I've found a girl cuter than you-chan lately. He says this without taking his eyes off you
