help me find this bl

they are friends who became lovers at chap 1 (i'm not sure). when the other friend of the uke found out, he invited the uke (or kidnapped, idk) and gangraped him (as i remember, there are 4 guys but idk if they raped him too) and the seme (the bf) saw him being raped (and this scene right here made me drop it, this was too painful to see). i just wanna know the title cuz it's been bugging me for days. thank youu
