The three of them are toxic in their own way.

Bye euchong is literally dojng nothing but getting assaulted how is HE toxic, the other two are literal rapists

can you explain how is eunchong toxic? the only thing i could think of is that he's a repressed gay man and even tho it's infuriating for some–that's something he gotta deal on his own and no one has the right to force him to acknowledge his sexual orientation that his friends had done.
