There was this manga where the uke had multiple boyfriends. The seme knew and was enduring. He even had marked his calendar on which day uke would meet with which boyfriend and prepare accordingly for him. Later the uke realizes he was doing the seme.wrong and breaks it off with his other partners.
I think it might be this?

I don't know if it's just me but I felt so so so bad when they showed Willy after he got caught ╥﹏╥ like I had nightmares for a few days (/TДT)/
