Mc hated his life before dying. Reincarnates in paradise world. Attractive natives all speak funny language and wear leaves instead of clothes. There’s free food from trees and ball shaped animals that are later eaten by MC for meat.

Mc likes a (purple?) hair girl and gets jealous of native dudes for being with her. He teaches the natives about fire, cooking meat, war, and other bad things.
Korean webtoon for sure, everything was full color and panels were spread out.
