Wise.

Vyse's appearance: male. Dark blue hair, somewhere below his chest, tied in a braid. His jacket was almost the same color as his hair, only darker and also fluffed up on the shoulders. He had a belt holding his pants up, almost the same color. He wore a regular blue T-shirt under the jacket. Height: 207-110

Wise was the astronomy teacher. He was one of the most handsome teachers in school. All the girls/men were crazy about him. You, at least, weren't one of them.

One Monday morning, you were in class. You were quietly chatting with your friends in the back row, thinking no one would notice. He walked down the rows, observing each group's work, and stopped in front of your group/desk [there was a group project].

Gentlemen, didn't I tell you to do a project and not talk with your friends off-topic?

He tapped his fingers on the desk and his voice was even.
