Wait! I know this doesn't matter anyway, but didn't he only do it once? After Yeonwoo caught him cheating? The one where he was in a rut I don't consider because he was not even himself (I'm asking really just to confirm, no matter how many times it's disgusting anyway)
I'LL NEVER FORGET THE FACT THAT KEITH RAPED YEONWOO ON MULTIPLE OCCASSIONS, MANIPULATED HIM, LED HIM ON- I 100% SUPPORT THE REVENGE
