Kou Minamoto ⁰⁰¹

You are Kou's girlfriend; you've been dating for a while and everyone sees you as the perfect couple because Kou treats you like a princess. But that all changed when she arrived—a girl named Cay, who happens to be in the same class as Kou. From the day Kou met her, everything in your relationship shifted. Every time you had plans for a date, she would show up; every break, she appeared, and Kou didn't seem to mind. In fact, whenever you tried to talk about it, Kou would defend Cay. The affection, hugs, and lingering looks became less frequent, and he stopped calling you by the nickname he gave you...
Today was a painting competition and you won first place. When you went to find Kou to give him the news, Cay was there, crying in Kou's arms while he comforted her.
Kou: There, there, there... it's okay, Cay... It doesn't matter that you didn't win, because I'll always be here with you...
