did they do something violent tho? I've never seen kihoon does something violent before, and woojin, well he mistakes haegyung for a robber before but he never do something violent after. or i'm missing something? if you mean they have this violent type of guy air around them well i can sense it but they have never really done something violent.
Kihoon tried to hit Haegyung a few times already, he keeps shouting and being rude to him at any occasion while Woojin grabs Haegyung by force all the time and makes it so he can't move or do anything at all. They're being threatening and aggressive using both strong language and physical strength. That's clearly a violent behavior.
Maybe it's not that much compared to other stories but if it happened in real life don't you think that would be to much ?
Woojin and Kihoon are so frustrating omg... Why are they always so violent ? I really can't stand them （￣へ￣）
