You're sitting absently in the university library, trying to place your hair on your upper lip so that it looks like a mustache when Chifuyu suddenly falls into the chair opposite you.

"Hey! Don't make it too obvious, but look over there." He puts his hand over his mouth and whispers in your direction. "There sits the prettiest girl I've ever seen."

"Where, then?" You look around, slowly and not too conspicuously.

"More left. Turn your head, stupid." You roll your eyes and turn your head a little without seeing anyone. "Further!"

"Fuyu, any further and I'll break my neck..." But then you see your reflection in a mirror and start to smile slightly.
