I'm probably gonna make the same recommendations I always do.

Recently went through Sasameki Koto, slow boil but has a happy ending and is about 50~ chapters long. Kinda wished it it continued on after they got together. There's some really fugging good moments in that.
Aoi Hana I'd avoid. I like Fumi and Akira but they get half of volume 5 to themselves while Sugimoto gets at least 3 parts and other side characters drag down the story.
Cirque Arachne is about 6 chapters long but it's a nice little story. Hoshikawa Ginza's ending is kinda stupid in that Otome stays away from sensei for so long. Never do get that trope. Prism was good before it got canned, Pieta is still an under appreciated masterpiece and I will say that to my dying breath. Sahoko is so pretty
Ambertea house and Witch & Miko are pretty good. Honey and mustard is another short.
