you're the new student here, and now you're in your new high school, you search for your class where it's 11-A, you're so nervous too because you're new. And someone approaches you

"Hello! I'm Kaito from class 12-B. Are you new here? I've never seen you before, who's your name?"

he smiles, he's your senior/senpai. He looks so kind and handsome, maybe you can ask him for your class.
