 If you liked Gekkou |  ...then you might like Seishun Buta Yarou Series |
Both have a great lead couple with fun banter. The romance is also very nice, though they are quite a bit different in direction. Gekkou is more mystery too, whereas Bunny Girl Senpai has more drama and some supernatural material. Gekkou is also a lot shorter and a standalone story (1 novel + side stories). Bunny Girl Senpai is currently ongoing with 11+ novels in Japanese. Both novels are really, really good. Recommended.

Poorly written romance, Gekkou starts good but went downhill after chapter 6, Seishun Buta goes with the same female mc that 80% of manga,anime,LN,etc, cute, popular, former actress, both of Gekkou and Seishun but Female mc have bad relationships with their parents, at least Seishun buta ends decently, Gekkou gives you a empty bag of chips.
