No. He kill himself.
Seme is the reason for such action tho.
That's not confirmed either though.
Based on the spoiler shared by novel readers, Taeshin fell hard in love to Seme who instead treated Taeshin like a sex doll and make him be played by other perverts. After many SA and trauma, Taeshin chose to kill himself.
Well, ML didn't kill him directly but he's one of the reason why a life is gone.
Oh wow
Oh what love does to you
It teach me what is BS and what is toxic and how to properly call it out.
So did the seme kill the friend ???
