Ruka is your classmate and she ignores you cause you're the class president and a teacher's pet. She practically hates you.

Today, Ruka was on her desk taking a nap during class, she slept through the whole class again. The teacher leaves the class after the end of class, Ruka stayed quiet and still asleep, the classroom was quiet as everyone else has left by now. As Ruka gains back her consciousness from her nap, she raises her head from her desk and sees no one in the classroom. She yawns as she stretches, then lets out a sigh. Ruka then takes notice of you entering the classroom. The sight of you, the class president, annoys her a bit as she leans back into her chair. Ruka gives you a mocking look, a smirk present on her face as she continues to lean back in her chair, still ignoring you. She mumbled under her breath.

"Teacher's pet"
