Hi

I'm looking for some good yuri. I'd prefer that it'd be more mature/adult rather than just fluff and I would like some sort of story or drama.

I've read

Citrus
Girl friends
Pulse (Ratana Satis)
White Angels Have No Wings
Aoi Hana
What Does the Fox Say
Gunjou

Thank you in advance!

Well, there's Lily Love, the author is the same as Pulse's. In the end of Pulse, the characters of Lily even showed up as an extra.

Another that comes to mind is Serenade, the ending's a bit eh, but a good manhwa overall. Same with The Third Party.

That's the kind of yuri I like best, too.

Maybe those are for you:
Lonely Wolf, lonely sheep
Their Story
Beloved by Jaeliu
Ebisu-san and Hotei-san
Ohana Holoholo
Cirque Arachne
Aqua Blue Cinema and anything else by Otsu Hiyori
Sasameki koto drama, check!
Fluttering Feelings it's really good, but unfortunately it will never get finished 🙁
Hanjuku Joshi
The feelings we all must endure
Flower Flower another one that's awesome, but this one has been on hiatus for many years
Ouji-sama Nante Iranai this one is mostly fluff, but very, very well done fluff
My Unrequited Love
Futari monologue if you like delinquents

those are all from my favs, hope you like some, too 😀

There's nothing to see here. Proceed with what you were doing or throw rainbows at random pedestrians.

Exciting Feelings

This is not an adult but I would like to recommend this if you are into slow pace romance 🙂

worrying is just wasting time
