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.
