help pls i forgot the title

i actually read this manga a few months ago and i forgot the title, so i only remember a scene where the uke thinks the seme is cheating on him so like every typical uke, the uke got jealous and they started doing it , and the uke started bleeding on his butthole and the seme said him to stop and then the uke said i told you i'd kill you if you cheat on me oh and also the uke was taller than the seme the seme was pretty short (=・ω・=)
