Yayyy thank you, im not talking about blue project but thx they weren’t actually cats they could transform into them
Idk what the second one is but maybe the last one is this? Not entirely sure though https://www.mangago.zone/read-manga/kuroneko_kareshi_no_asobikata/
Yesssss thank you
So here’s the first one
It’s an alpha and omega world and two person got married, arranged marriage i don’t remember much but the bottom has brown hair and the top has black hair. And uhh the bottom thought they couldn’t produce pheromones but he could, and I remember a part where the bottom, his husband brother wanted to assault him in the bathroom i don’t remember much sorry.
Second one is a girl got transported into a world and she was uhh, walking with a group of guys because it’s a monster world and they wanted to have sex with her but she lied and said if she loses her virginity she’ll lose her healing power and they said oh let’s do it in the ass instead and the demon king came and save her
Last one is omega and alpha again but this time it’s cats, and uh the mc who is a black cat is with a leopard or it’s vica-versa i think. And uhh, the ml is a white or blonde cat.
