Yep in my opinion he groomed both of them but as cheeky as it sounds may be he fell in love or whatever shit with jekey so that's y he felt jealous whenever jekey was with v .
I also think jm's handler was maybe Mr or sug@ . What's strange is that if we say that they were underage at that time couldn't differentiate btw taken advantage of and love . But now they are grown a$$ men . They should feel disgusted toward their handlers but they are more close to them like in case of j!nk00k and I also feels jm is very close to turtle and sug@ . But again it's just my assumptions
I am not into the shipping thing, but you know what you said is still very important. I should find again the video on a very good channel speaking about Mk ultra and others stuff, but unfortunately I just remember some extracts, I hope I can find it again in my historic.
It explained well that a lot of celebs under the authority of the handler, can often falling in love because of the bad environment and the abuse. It's more of the victime's side of course, plus a mix with Stockholm syndrom. It could be the case with some members you quoted. It's possible. And sometimes it could be the handler and the victim who fall in love. It was an ex agent whi explained this. And it happens a lot of time.
I don't dare to imagine the mess in their world. Really. And for Jimin, I think the same. Rm and Suga looks like handler to him. More Rm if you want my point. Dude is always touching Jimin in a weird sexual connotation
