okay guys - there was this one BL manga that was kinda cute but I can't find it in my list, I'm not sure if I remember everything correctly though; there was this one boy (mc, blonde & young) who's form is an animal, something like a leopard, and he was sent to earth in that form as a punishment (his original form was a being with wings). he was punished because he tried to save someone dying (since he wanted to change their fate). so one day a man (black-haired ml) finds him as a baby leopard on the streets and raises him and stuff, then idk what happened in the meantime lmao, but they ran away together from the other beings who wanted to take mc back since his punishment was over but in the end he tries to save ml this time, so he makes the same mistake again, thus get's punished again and they end up together on earth - oh and I remember something about the boy painfully growing his wings back and hiding it from ml
