whattaWonderfulWorld's Manga

this one actually had a decent story line, i'm on chapter 85 and going strong

This looks wholesome

I think, at first you need to be patient because Jiwoo (MC) is new to this world and he needs to develop his power and also his mentality. more you get into the problem and the story, and that's when jiwoo start to grow and become more and more appealing.
