Riku fucking the dude that drugged Ryo pissed me off way too much

I dont know how to do the spoiler tag so this is a warning




IKR?!?! Like yeah I'd still be pissed if he had sex with another dude but they arent in a relationship so ok but with the guy who DRUGGED your love interest? huh? that was so offputting I thought he would get revenge on him but just let him suck on his cock as a reward
