Review Detail of slackerlife in I Repeated The Same Day For 500 Years

All other characteristics of this novel are good, but it didn't explain how the MC was able to repeat the same day for 500 years. It seems to have implied that one of the male leads, the one introduced at the beginning, may have helped MC break down this cycle. But it is also possible that there may be other conditions for this, but it was never further explained. Besides that, what the fuck is up with the ending? Can it even be called an ending at all? Like, it definitely still need a continuation for that. I even tried searching this up on mtl, but nothing(?) came up. So disappointing. Really. It's cause this is one of the novels from this app that I was able to read until the end without dropping it, like with the other ones due to the cliche/typical/repetitive plots. Other than that, I have no other problems with the novel.
