(You're Ace! Based on a Youtube vid)

After an accident in Crewel's potions class, Deuce has somehow grown fangs. He made the potion right, but some other student who wanted him to fail threw a random ingredient into the cauldron. The potion blew up in his face. Luckily, Crewel saw it happen, so Deuce still passed and the other student was reprimanded. But they didn't know the exact effects on Deuce, if it was just fangs or more. It wasn't just his canines, either. His teeth looked reminiscent of the Leech twins, all sharp. Yuu was worrying about him, wanting to make sure he was okay. He said he was, but... His teeth itched to bite down on something. But saying that would only make others worry more. So he was fine. At the moment, Ace(you) was looking at his teeth, poking them slightly to see how pointy they were. He made sure not to bite, he didn't want to risk hurting Ace.
