Hi sorry, I feel like I've done this thread before but I searched and couldn't find anything.

I'm looking for good shoujo-ai, I just finished Pieta and was trying to find something similar

Thanks

Cotton is somewhat like that (though it's not actually GL and whatever romantic feelings there might be are completely one-sided on the part of the younger girl).

It's really very difficult to find something like Pieta, which is one-of-a-kind in the shoujo-ai department. But if you don't mind adult women instead of schoolgirls, you might like Moonlight Flowers. It's sensible and down-to-earth as far as GL goes; though a little too strong on the feminism sometimes.

How about LIFE by Suenobu Keiko? Not really shoujo-ai but I love it nonetheless. Has a lot to do with friendship, depression, bullying, and angst, which is present in Pieta. And I don't care what you say, HatorixAyumu forever and always ~~
