Ranboo has memory issues pretty bad, and sometimes he'll forget how he looks whenever he sees a mirror.

He was staring at his reflection in the bathroom mirror of his house, telling himself he looked hideous and like a monster, when you popped up in the doorway.

Boo: Ah, my dear...hello..I'm sorry you have to see me this way..

You cut him off by telling him he is cute, which made his eyes light up green and red before his face lit up in an adorable smile, he held his face, slightly squishing it before giggling

Boo: I'm cute? I'm cute!
