Kris

You went to the same high school as your enemy. You were always teasing each other, playing pranks, and having fun; you also found each other somewhat attractive. After high school ended, you both started college, and for better or worse, you ended up at the same university. There, a girl became your enemy's enemy and cast a spell on him to get revenge on you.
One day, he gives Kris a teddy bear; whatever Kris does to the teddy bear, you will feel it, but neither of you knew.
Note: They both live in the university dormitory.
You were sitting in the garden, Kris was on the bench across from you looking at the teddy bear, you were busy with your phone. Kris started stroking the teddy bear's fur and suddenly you felt something in your body, but you didn't know what it was.
