Can someone help? I remember a smut bl yaoi novel I just remembered one part where they had to act as fantasy characters. One person was the bird, one person was Cinderella and the MC was in a maid dress and the ML was a butler. There was some timetravelling or parallel timelines and the ML had to do kinky stuff like checking the MC's underwear underneath the maid dress. I believe it's ongoing and world hopping or unlimited flow BL. He also had to run to the ML every night to survive the world, it was either spend a night with the kinky butler or he may fail or die the survival world. And at one point he asked the ML if he remembered him and the ML was like "which one? The one that sat on my lap and did x kinky things or the other one which did Y kinky thing?"
