Star X Fanboy -
it's ongoing, but it's like the gift that keeps on giving. It's so pure and gentle and there's so much of character development.
Jazz For Two -
the angst is there, but for the most part, it's really cute and even a little sensual at times.
Path to You -
still ongoing, but it's really sweet and the attraction between the two leads isn't forced at all!
Till Our Lips Touch -
this is honestly one of the sweetest ones i've ever read, and there isn't too much of drama, so it's a relatively light-hearted read.
Tadaima, Okaeri -
Tooth-rotting fluff. Be prepared for one of the cutest stories you'll ever read.

It’s a yaoi, but it’s so heart warming and adorable! The art is so warm and cute, and the relationship between the seme and the uke are amazing..!
The Story of You x Me
so sweet and funny
Xxx series
horimiya is no joke the best slice of life manga ever. It’s about a girl named Hori getting with a guy named Miyamura who looks like a nerd at first but actually has piercings and tattoos and he changes from being gloomy and alone to being surrounded by horis family and friends.
Since everyone has recommended some I've read already,,, Rain Again!!
Fluffy, cute, heartwarming stories. Preferably those that aren't one shots
