Looking to read some of the more "out there" romance concepts, and thought I'd post here instead of praying to RNGesus and just doing a tag search. I have three examples of the types of "vibes" I'm shooting for, but honestly interested in anything that isn't just a bog standard romance series.

I'm interested in stories that have some strange concept or dynamic thrown into an otherwise normal romance (the stranger, the better), such as Nazo no Kanojo X, stories that take a more psychological and/or dark approach such as Aku no Hana and Oshimi Shuzo's other works, or stories that work with some creative and more elaborate setups such as some of Shinkai Makoto's works even if they aren't perfect in execution.
