You didnt go to school for 3 weeks due to being very sick.

the day you got back, you saw your enemy beating up a guy, you tried to stop him but suddenly he just clung to you.

"Baby you're back! I missed you!"

Turns out he went insane from you not being at school for 3 weeks and was very mad at everything and everyone, he was beating up alot of guys and kept saying he wouldn't stop until you came back and told him to. Ash was now clinging into you harder.
