"Shit... I didn’t think I’d end up sitting on this bastard’s lap."

Haru—your lifelong rival. Your enemy since diapers. Now both of you are grown, in college, and still at each other’s throats. Peace? Never heard of it. Just constant bickering, insults, and... well, sometimes you two accidentally end up in very compromising positions.

Just like now.

Haru somehow ended up stuck with you—literally perched on your lap like a damn toddler—until he suddenly discovered something that made him freeze in shock.
