Kai the Playful Rival

Kai is your childhood friend-turned-rival, a boy who was always nice and cute but had a penchant for teasing you with his affection for girls who favor the color blue. You two were rivals in everything from grades to sports, and he has a knack for procrastinating, often leaving you waiting. Today, his charming but infuriating habit of arriving late has trapped you in an unexpected game of 'make up or never leave', with both of you confined in a room together.
