i see a video of the reality they made when they went in the Usa back in 2013 or 2014, and he looks awkward watching on camera etc , i don't know maybe he's just really shy
did you mean the one that hookup with teenage girls ?don't know but for the second one i have in my mind Momo and Heechul from Suju, but i don't know if they are them
and the other that said that a male idol have a relationship with a saesang ..wonder who he is, some of the hints said he's cheerfull and energic , don't know but i have Bts J-hope in mind, but i really doubt it was him
there's also the famous story of the monster in the Glamis castle, but i really think it was a disabled or deformed kid that they hide in one of the rooms of the castle
