About Kim Geon Woo, you can find several claims/declarations from both sides. I honestly won't form an oppinion based on that, cause it can be interpreted in both ways. I read the claimed victim won't take it to court to protect all the victims from further harm. Which i can totally understand, but in my oppinion court is the only way in which this situation can be cleared up. So I won't take any standpoint in this.
I can only say rumours spread like wildfire and if an accusation is found false, the damage is already done and the truth doesn't always spread to everyone who has heard of the rumour. For example the rumour about Shaun.
