I just had this sudden thought that what if the girls are a reflection of the guys’ innocence and youth. The whole theme of hyyh was growing up after all.
Tae was protecting the girl from getting arrested, so he could have been protecting the small part of innocence he had left (he did attempt to murder his father after all, and has been through child abuse). And then the other girls also had something happen to them. This could mean that the members got their youth ripped away from them.
In Jimin’s case I think he lost his youth long ago, something happened to him in the past. But he’s still trying to act like he’s fine and probably admires Hoseok’s innocence. He’s basically lying to himself and the people around him.
These are just some of my random thoughts and I’m probably way off, but I tried.
