V didn't mean to lose control , he didn't ! It was Jin's fault , he was the one that made V do it in the first place . Jin was teasing V , how could V not Grind into him on stage ? unfortunately for them every member of their band has their own problems and this makes everyone snap and split apart into separate groups . One loved Jin , one was looking out for the previous guy . One was trying to keep the band together , the next one had no clue what was going on . One was struggling with depression and both V and Jin were caught in the middle of it all .
