Oh I like this take. Definitely agree that Jingi's hypersexuality stems from his childhood trauma.
After ch 87 It's interesting to see how the Jingi/Myeongil dynamic is shifting (JG avoiding MI and MI looking for JG). I think part of JG's reluctance to give money to MI is also because he doesn't want MI spending it on Heonjae (thus his delusions about their post-prison newlywed life lol).
I'm glad we're back to the prison setting. Sex or not I think the development there is wayyyyy more interesting than what's happening outside with Heonjae
Couldn't agree more, though I'm a bit worried that the prison era's about to end soon since the current timeline is around the end of April, and Myeongil is set to be released in May.
Myeongil and Heonjae are probably going to be attending the school’s track and field/children’s day event in May, and that’s probably where the uncle spots them since his kid goes to the same school. That’s likely when he would start preying on Myeong’s sibling.
As for Jingi, I kinda have this theory (secretly hoping) that he’s going to run away during his outside work. It just felt way too specific for Myeong-il to bring it up in CH 85 if it wasn’t going to matter later.

In light of jealous Jingi making an appearance, it's so interesting to see how the brothers respond to jealousy and stress in very different ways, which seems to reflect their respective upbringings. Heonjae tends to react with aggression and violence, even to the point of extreme confrontation (aka attempting murder on Jingi), likely due to being groomed by his uncle to be that way. Jingi, on the other hand, appears to default to sexually charged behavior under stress, likely due to having hypersexuality as a result of csa.
