Rather, it's a story about the heroine forcing time loops in order to change the villainess's fate. Although she "chooses" capture targets in each loop, she doesn't get romantically involved with them. It's all for the sake of Choko (the villainess).
I like Kurando (Janitor-san) 's character, although it's a little hard to get a handle on it before other characters are introduced. He has a good grasp of his own weaknesses and has the mental maturity to look out for himself instead of blundering around like a naive brat. He places a lot of value in promises, even if he is realistic enough to realize that not everyone will keep their promises.
Time passes fairly easily; it isn't one of those stories where there's a ton of action and only a week has passed. The time passing doesn't have the sudden feel of a timeskip, either, and it's not as if he's suddenly super OP after a few months of closed-door training. I like it, at least.
In hindsight, this story was great until he met Yue. It was a gritty, fight-for-your-life survival. And yet the author decided to turn him into a chuuni nightmare (for us) --WHILE acknowledging that it was chuuni. At the time, I was caught up in the addiction of reading chapter after chapters, so I didn't even realize how stupid that was. But now...
Moving on, it went from great to good after leaving the 1st dungeon. Then it went from good to okay, and okay to "why the heck am I even reading this?" I really wanted to know what happened after they reunited, though, so I kept on reading.
When he meets the girl from his class again, I'd say that's when things were really ruined. I got the rabbit girl clinging to him. She didn't seem to be the brightest, and was a persistent girl. To be honest, I always thought she was just mistaking other feelings for love. But that chick from his class?
I've never understood devoting yourself to a man who you love, but obviously has someone else he loves and is sleeping with. Correction, a man you are infatuated with. Because I don't think that it can be considered love when it's entirely one-sided on her part.
Anyways, when it hit the underwater arc, I just couldn't take it any longer. I stopped reading the raws back in 2014, and then blasted through the translations a few months back. And after that, I decided that it wasn't just my shaky understanding of the story--it was really, incredibly boring. Too many power-ups, too much OP.
The realization of the harem just ruined it for me. Not the fact that there was a harem–I can deal with that–but the way things played out. To me it felt like the author kept on shoving the fact that the girls’ relationship with the MC had become s*xual in the readers’ faces ALL THE TIME. It got to the point where I couldn’t even skip over those parts because it was mixed in with most of the normal (pre-romance) content.
After the harem was realized, the rest of the story (battles, training, even new characters) became inseparable from it. As a result, I’ve stopped reading it (mostly lost interest) ; however, other than that, highly recommended.
