No cause why he acts like a selfish baby every time. He's definitely a psycho. The only way I could maybe understand his stupid behavior in this chapter would be if that blond guy is actually more psycho than him (gun and cage in his apartment) and JK knows how crazy he is with his lovers so wanted to make it clear he should NEVER approach Dan with that kind of intentions. What if blondie physically hurts and abuse his lovers? Like in a terrible way! They hinted a bit abt this in their last conversation. The author should hurry up and give us a bit of backstory for JK. More than 30 chapters and we still don't know shit abt his past. It's just ridiculous at this point
hes so fucking jealous, hes acting like a fucking baby omfg hes so fucking stupid
