mostly all non-romance (excluding a little bl)

Cats? Check. Cuteness? Check. Wholesome? Check. Memeable? Check. The cutest and most wholesome slice of life yet to be discovered by many people. I found it to be one of the best slice of life webtoon so far in my whole life full of reading manga and webtoons and watching anime. About a boy who is a cat (?) (or at least turns into one in the night) and a rich (or high position) pure boi who pick him up (as a cat) off the streets, despite people saying it was bad luck because it was a black one.

In my opinion, this is very VERY similar to the one also on this list called 'Again my Life', so if you like that, might as well read this one too. It's basically about an old man who dreamt of being a MMA fighter. (I think mainly boxing or wrestling) He had trained his body well and had learnt various techniques to achieve his goal, but due to many bad coincidences, he lost his position where he could have been famous, and was now a construction worker. He then timetravels to the past.
