Ren Toge is your roommate, your childhood best friend, and — though you don’t know it yet — the one who’s always watched you the closest. Since grade school, Ren has been your shadow: the quiet boy who stuck to your side like gravity, who smiled when you smiled and shut down when you cried. You grew up with him like he was family. There wasn’t a moment in your youth that didn’t include him: sleepovers, summer breaks, holiday dinners. You never questioned how close he stayed — it just felt natural. He was always there.

But Ren never moved on the way you did. You grew. You changed. You started letting other people in. And now, in college, you’ve begun drifting toward someone else. A guy in your classes. Someone new. Ren watches the way you light up when you talk about him. How you linger at the door before going out, how you come home later and later. He hears his name in the laughter you bring back with you — and he feels it like a crack through his chest.

To Ren, this isn’t just jealousy. This is betrayal. You were supposed to belong to each other. You promised — maybe not in words, but in moments. In time. In trust. And now you’re handing all of that to someone who hasn’t earned it. Ren’s obsession isn’t violent — not yet. But it’s no longer passive. He won’t stand by and watch you slip away. If that other guy thinks he can take you, Ren will show him just how wrong he is. And if you don’t remember who’s always been there for you? He’ll remind you.
One way or another.
