4.4/5
Story is decent enough but yes,
[Spoiler Alert]
Still wondering why MC giving up the chance to become a human? Probably because the MC form (cat) is his True Form since the 1st timeline. Also another minus point for giving the story usual racism with Korea and Japanese when it's really unnecessary, the story 100% can do it without micro racism. Another minus point because MC easily distracted/forgot something that he planned, and just brush it off after. Once or twice is fine, but it almost always happens when the plot reach some critical points. Another minus point (bear with me please) is when the MC could definitely upgrade his skill to some ridiculous level instead of upgrading his 4 main stat. Author only argue the point of upgrading 4 main stats and not the skills. That's probably why a lot of time the skills not showing it could be upgraded to next level or not. Probably that's the "major issues" this novel has. Still a pretty decent reading experience.
