True. But I don't think inseo considers him as a friend really to begin with, when they showed how they met he was kinda pissed when sanho and tak approached him and hyeok, but Ig he just went with it cuz hyeok became friends with them and he just doesn't mind them but he doesn't really care, he seems like the kinda person who doesn't care abt anyone or anything but himself, yi hyeok is becoming an exception apparently, and even so, Ig that's why sanho went to warn hyeok abt the kinda relationship they're having
Anyways, even tho sanho was upset and they did go all the way it was still unclear, sanho said something like he should've run when tak started flirting or something like that so maybe he got swept away in the act and regretted it later.. or maybe not, again the author didn't show enough to know for sure that it's a rape, and I'm hoping it doesn't end up being a rape TT-TT that's why I'm dying for more details!!
M really worried abt their cute friend from that tak like seriously.. I hope there's no rape in this m done with forced sex in every yaoi
