It's a bit too unrealistic for my taste. I mean, not that I mind fantasy or isekai, but the world is so surreal and artificial, I can't really feel immersed in the story. It'd be fine if it was like sci-fi/mystery or something, but for a romcom, I'd prefer it if it felt more internally consistent. Also, even within the setting, it's like the author couldn't come up with a plausible reason for him to revert to his earlier stats, so they just ignored the problem and reset him for no reason at all. That's just sloppy.
