It should have just involved a regular korean gang rather than Japanese yakuza. I feel the author's racism this chapter. I know there are Koreans who hate Japanese people and this author seems like he might be one. I hope not though. Racism always ruins a good story.
this feels like implicitly saying that there will NOT be a harem ending. F (unless I'm overthinking it but jokes aside, it's not like there was a high possibility to begin with lol)
