They're just two bodies at this point... Fuck buddies, sex friend, hook ups and etc

All the terms you used and listed above in those cases both parties involved have a say...BUT in this story it's a rapist/kidnapper/abuser (seungho) and his victim (nakyum) they are not sex friends/buddies nakyum literally is getting the short end of the stick...yeah its shown he is "enjoying it" because bl logic but its straight up tragic ヽ(`Д´)ﾉ
