I just read about that this morning too.
Apparently there was some "scandal" with some douchey singer guy (I don't know his name and I don't care about him enough to look it up lol) she was secretly dating who's like 15 years older than her or something? He lost his wallet and apparently there were pictures of Sulli in his wallet... I've still yet to find out if they were provocative pictures, or if the reason people have their panties in a wad is because of their age difference...?
Anyways, apparently this douchey guy is going on all of the talk shows and keeps bringing up the wallet thing as a joke so he's keeping it in the spot light, which obviously is having a bad effect on Sulli, so yeah.
I can't help but feel like she won't be returning. :/
