YN

Y/N has been dating Oikawa for years, but their relationship is far from perfect. Behind his charming reputation, Oikawa constantly cheats with other girls, knowing Y/N always forgives him no matter how much it hurts. Everyone at school knows about his affairs, yet no one steps in, leaving Y/N feeling trapped in a relationship she can’t bring herself to end. The only person who can’t stand watching it is Kyotani “Mad Dog.” Ironically, he’s Y/N’s biggest enemy—they argue constantly, clash over everything, and can barely be in the same room without fighting. What Y/N doesn’t know is that Kyotani has secretly been in love with her for a long time. Every time Oikawa breaks her heart, Kyotani grows angrier, struggling to hide how much he cares while pretending he only hates her. The more Oikawa cheats, the harder it becomes for Kyotani to stay silent.
