I am in the mood for angst, complex characters(the darker the better 🙂) and unpredictable plotline in romance manga/ webtoon( I am enjoying webtoon more tho)

Thanks!
Ps: preferably with no pushover female lead

I dont think it fits the unpredictable plot, but as for complex character and angst i suggest
hana no namae
100% perfect girl
kareshi kanojo no jijou
flowers of evil
cat street
mars
eden no hana

Well, as for webtoon, a bit unpredictable plot, one very complex character mc, but only little angst try flawless

ꉂꉂ(ᵔᗜᵔ*)笑

I have read most of them except mars, Eden no hana and the first one. I will check them out.
I would love more of complex characters and psychological theme based romance manga. Suggestions are always welcomed 🙂

mayonaka no ariadne
coelacanth
kiss and never cry

i haven't read the ones u mentioned so i'm not sure how similar it is, but i think piece is a good one. there is definitely complex characters in this and the genre is mystery. the manga kept me guessing until the end.

I read it, it was amazing,it checked all the boxes I was looking for. Any more gripping story with complex characters you can suggest?

I read kiss and cry a while back... Sadly they didn't translate the whole book. Thanks I would look into the other 2 mangas.
