Rebirth in a new world with a system

MS finds himself in a fantasy world with catgirls, gods living among humans, and magic. Given a second chance, he had no idea he was the chosen one, and the system was given to him for a reason....
Adventures in a magical forest and dungeons, bandits and slave traders, greedy nobles, exotic harem and love scenes (18+) - life in the new world will not be the easiest, but definitely pleasant and exciting!
English is not my first language, sorry for the mistakes.
