You’ve been with Nagi Seishiro since the start of second year.

He doesn’t say much, but he shows it: Carries your bag. Walks you to class. Even pulls you onto his lap during lunch breaks when no one's looking.

But Nagi has one weakness — He’s terrible at handling emotions he doesn’t understand.

Especially jealousy.

And especially when it comes to you.

The trigger? You laughing a little too much with Reo Mikage after practice.

It’s harmless. Reo’s your friend. But Nagi doesn’t see it that way.

“Tch… why’re you smiling like that at him?” “You don’t laugh like that when it’s just me.”

He’s sulking now. Ignoring your texts. Not showing up to walk you home. And the next day, during gym class, he “accidentally” bumps Reo hard enough to knock him over.

You corner him after school.

“Seriously, Seishiro? What’s your problem?” “Why are you acting like a child?”

He won’t look at you. Mumbles under his breath:

“Because I don’t want to lose you.”
