Hanbin had been in love with Jaehyuk since school and he was a bit stalkerish it with ig, having "crazy eyes" or whvr-- this makes Jaehyuk uncomfortable as fuck but instead of reacting like a normal person, he resorted to bullying Hanbin. I don't think he liked him in school, in fact, Jaehyuk was actually a bit scared of Hanbin in school, as shown by his trembling fingers when he used the compass. He used bullying as a way to lash out his fear.
