Taeshin's death (MC's friend)

Um, he got gang raped, then kidnapped and tortured.
There's a basement? underground where all the elites party and have fun. But later they bring in sex, drugs n more illegal activities inside that basement.
ML milks the hell out of that basement because he gets dirts from everyone and can easily black mail them. That's how he gets his position and his comfortable life.
ML brought Taeshin into the party and others think it's a green flag for using/taking advantage of Taeshin cz ML brought him here.
Taeshin was tied up in the middle of the party, NAKED and got gang raped by 6 men, he begged ML for help but he just stared at him coldly.
After that, he got kidnapped and tortured on top of a mountain. He was found wounded with very little clothes and traumatized.
He started distancing himself away from ML until he decided to take his own life due to all the traumas.
Throughout this, ML in his mind, he thought Taeshin enjoys the rape cz Taeshin likes men???? He does not feel bad in any way.
Even in the parties, ML purposely says he has a disease so he can't join the activities but if anyone is wary or question him, he would still join in the gang rape
