ty for trying but that's not a manga TwT
all i remember is that the seme suggests using a blindfold during sex and the uke starts freaking out/panicking because he had a bad experience with blindfolds. (seme does not know this until uke starts panicking)
the bad experience was that he would go along with anything his ex (not the current seme) wanted in bed, mainly all BDSM related kinks. one day, his ex blindfolded him and he was fucked, until the blindfold was taken off and it turned out to be someone else fucking him and his ex said something along the lines of "you're such a slut that you couldn't even tell the difference" or something like that
this probably happened like mid-story, besides that i don't remember much else.
