I don't think it was all because of Suju's fan. That girl already had problems to deal with BEFORE she even took the pics. That girl was already dealing with stress and was also harassed at school. (because of her weight, etc) Suju's fan harassing her put more fuel into the fire. People keep saying 'oh it's Suju's fans fault' guess what? IT'S NOT ONLY THEM. She had personal issue in her own life too. People just blame it on Suju without knowing the full details.
oh and the person she took the pic with is kangin <33
If I were you NEVER EVER trust PopSeoul for their news. They twist up the news and stuff. Take that site as a joke and just use that site for amusement. Never take their news seriously. They don't tell the full story, and twist it up making the artists look bad. (especially with Suju, they dislike Suju which is why they bad mouth them all the time)
And about the girl you said in Suju's 'U' mv, her name is YoonA and she's from So Nyeo Shi Dae which is the new girl group that recently deubuted under SM Entertainment. SHE IS NOT LEE SOO MAN (owner of SM) niece!! I never even heard of the rumor
Also she's not the leader of SNSD is Tae Yeon.
About antis, they seriously need a life. Some korean antis AND fans just take some things way too far. But anyone that have fame, popularity, and fans ALWAYS will have anti fans. But it's not just in Korea, but other countries too, but you just don't hear much about it.
I think this is the longest post I ever made in AsiaJam >_>
