Can someone recommend me something like this?

you can try aku no hana from the same author if you haven't. also oyasumi punpun from inio asano is compared to this a lot

aku no kyouten gives off the same vibe as well

I actually saw the anime aku no hana anime and read the ending of the manga . And i ami currently reading oyasuminasai punpun at chapter 85

lol surprised but not really to hear that both authors are "competitors"
