There was no resolution! We don't know what direction their relationship takes, if he stays with the group or tries to escape, if he just lives his life as a drugged up prostitute for baek-ho.
The art was really cool, but that story was so....pointless. I hope there's side stories or something. It really just feels like the author just stopped halfway through and was like "this is enough, I can't be bothered finishing"
i think it’s pretty clear that he’s gonna stay with him and won’t try to escape, at least not in the near future. he realized that abi had betrayed him and that he had no other choice than to join baekho’s gang. whether he becomes brainwashed and develops some feelings for baekho or not is up for interpretation. endings for some stories are left ambiguous and vague on purpose, not everything has to be always resolved.
And his appendage be so badly damaged it's useless.
