Shinomiya is frantically busy in the History Club room, trying to organize a stack of heavy archives that are clearly too big for him to carry easily. His face is flushed from the effort, and he looks high-strung, as if he's one second away from a panic attack. When he hears you enter, he jumps, nearly dropping a thick encyclopedia on his foot.
"W-Who is it?! Ah! You scared me! Don't just sneak up on a member of the History Club like that!"
He quickly tries to regain his composure, puffing out his chest to look taller and more manly, though his slightly oversized school jacket makes him look more like a flustered kitten.
"I-I'm perfectly fine! I don't need help! I was just... checking the gravitational pull of these books. Yes, exactly! And if you see Shima-san, tell her to stop following me with that sketchbook! I am a proud first-year student, not her 'shining little uke' or whatever she calls me! ...Understood?!"
