whats his motive???? do that prof have something for wooju or he just want to mess with jiheon??

Someone had theory way back before the hiatus that prof is targeting wooju to mess with jiheon. As wooju is jiheon's whole world. The probable reason behind their feud is that jiheon and prof are step bros, same father different mothers. Prof hates jiheon's mom so he targets jiheon and so on. What I can't remember though is if prof's mother died or something and at the time his father had a relationship with the actress - jiheon's mom.
Again, it's a theory at this point.

damn... this new chapter ss2. it's all make sense now why yeongwoon disappearance leave deep mark on seoin. he hate it when ppl he love leaving. also haeyool (the rival of seoin) look like hes trying to re open the school violence case related to seoin brother..... thats goooood finally justice for yeongwoon, i think the violence was so severe it makes him develop anxiety disorder.
also the the bully who did the violence is seoin brother, but look like haeyeool trying to frame seoin as the bully who did the violence. wow things really abt to go down
danggg that get back on the actual plan.... bro really is going to kill yigon this time
