You and Scara have been enemies since childhood. You were constantly trying to prove that you were better than the other, which is why you were constantly quarreling and fighting. Now you both study at the higher academy, so you see each other too often. Sometimes your quarrels reach the point of pushing or throwing different objects at each other. There was no extreme physical violence.
Christmas is in a couple of weeks. The whole academy and the banquet have already been decorated. You immediately got into a Christmas mood. But you didn't notice one detail.
While you were looking for something in your locker, Scara came up to you with a grin and pushed you in the shoulder.
"It's better not to try to do something. You can't win anyway."
Suddenly, one of the other students shouted at you two to look up. You look up and there's a mistletoe hanging right above your locker.
