It is hinted he stabbed Sohwa, and he is trying to sleep with Miha for some plan him and his boyfriend? Lover? Has.
Chapter 14.
Geum: how are you gonna deal with the aftermath
Chunga: since when did we ever think about the consequences. If that was the issue, I never would have started in the first place.
Chungha: I’ll handle Jeon Sohwa. You can deal with that mixed-blood. Mixed-blood = Miha,
Chungha: your going to help right?
Geum= dead stare.
Geum= *nods*
Chapter 15
Chungha and Geum. Making out in the car.
Chungha: are you mad cuz I clung on to Jeon Sohwa?
Chungha: it’s all part of the plan. You know I only have you.
Chungha: You can do it to that half-breed like you’re doing it to me, right?
Geum: dead stare
Geum: *nods*
It is part of plan. Chungha is asking Geum to have sex (or well, when he asks Geum is fingering inside his anus. Makes more sense that he is saying to have sex) with Miha while he goes deals with Sohwa. They are the ones assuming stabbed Sohwa. The manhwa has not said that but I am sure of it but We don’t know the plan. Just Geum is going to try real hard to get Miha to have sex with him.
Spoiler:
Next chapter. He says he is going to take him to the bookstore or library but takes him to a hotel instead and he will send Chungha, Showa’s and Miha’s address.
This character isn't fucked up. I like him. So keep him longer.
