Its been a while but I remember it was a male protagonist who is in another world where there is a level system. It's r18 novel with sex scenes as well. At least 2 harem members, one was a cat girl and the other was a mole girl who had a tail for blow/suck jobs. I know for sure it's not on royal road, and I'm pretty sure it's not on novel updates either.
Started as an original in rrl then got a site on it's own. The main character is named michael. I don't remember the exact name, my apology
... is it really that bad? Haven't read it but from other people's reactions... I get the feeling I will waste my time if I read it.
Then here's something from a normie. They are really boring. Addition: The stuff is messed up, but it's boring.
