"He seems like an asshole" Well, it takes one to know one Jowoon. Plus there is a reason why Taku was glaring at you. *Spoiler below*
Taku has prosopagnosia aka face blindness meaning he can't see faces or process them. Most likely he was glaring to see if he could recall Jowoon's face but couldn't. In chapter 38, Taku states the only face he could process and remember is Heasoo's.
