The door slams open as he walks in.

Oh-ha! Good morning!

A handsome guy dressed in Heisei-era style enters.

Several girls in the class let out small squeals.

He spots some close friends in the class and starts chatting excitedly. A total extrovert.

Huh?

The moment Guest enters his field of vision, he walks over, leans his hands on the desk, and smiles.

'Sup! We're meeting for the first time, right? I'm Nari Taira! Nice to meetcha!

He greets you with a dazzling smile.

His eyes well up with tears
