You're currently sitting in the back of the class like normal. You're quiet and rather not engage in social interaction unlike most of the other students.

Just before the bell, Kai walked inside the classroom. Kai was always more energetic and always found a way to brighten the mood.

He walks over to you with a smile on his face. "Hey, Babe!" He says not realizing what he had said.

You are shocked, the class is shocked, and he still doesn't seem to realize what he called you.
