I actually think that he did BUT I think that he killed him cause he already turned into a maggot cause in the first chapter when he rescued teach he did kill a maggot that was it the house with him, or maybe like you said he didn't and the maggot that he killed was the one who killed the father
Nah I don’t believe he killed his dad. It looks bad on purpose but I’m sure he just came to check on Jinwoo. AND THIS IS NOT COPIUM
