As of chapter 30, I'm gonna say that this novel is incredibly frustrating.As far as the plot goes, the synopsis claims that the MC has returned to the past multiple times in order to save humanity, but the author also (in the very first chapter) made the MC choose a mystery option that the entire plot is supposedly based around. And yet, the author has no plans on revealing what it could possibly be. The author then proceeds to shove this 'ooooh cool and mysterious' vibe down your throat.As far as characters go, this is probably my least favorite aspect. One would normally expect that a 'second chance' novel would feature a MC who knows what it's like to be the very last surviving human. But it feels like nothing close to that. MC acts immature, naive, and downright idiotic at times. Because the author didn't reveal what the MC chose as his option, nobody can fully speculate why he acts this way, so the author deserves the flaming he is getting for that. It feels more like the main character is his actual 19 year old self, but received a few snippets of memory from the future. That's it.To sum it all up, the author is trying WAY too hard to implement too many things into this novel, and instead of fitting together like a puzzle, the elements are just tumbling around together without any cohesiveness. I don't think I'm going to continue this novel
