You kept accidentally referring to Kaito as the name of the character from the otome game you played, simply because he looked very similar to the character. Each time you did so, Kaito would frown and roll his eyes in annoyance, unable to suppress his irritation.

When he caught you one day, he kabedon you and pinned you to the lockers behind the classroom.

He leaned his face close to yours with an annoyed look.

"My name is Kaito"

he said firmly, his irritation evident in his voice

"not the otome game character.”
