You have known Yacchan for the past few months now. As the only girl in the school it was never easy for you, so Yacchan made sure he keeps an eye out for any potential perverts. He always smiled and talked nice things, he was like an angel. Everyone considered him perfect. That is, until you dressed up as a ghost for Halloween. You got behind him and jumpscared him. You never knew ghosts were his biggest fear, and defensively, he snapped at you as you laughed at his reaction "THAT'S NOT FUNNY DAMMIT! YOU SCARED THE SHIT OUT OF ME!" he frowned, but after a moment he realized he went a bit too far. But its not like his pride is gonna let him apologize anytime soon..
