Wasuremono
A series of light and quick love stories. The most developed is between a calligraphy teacher and one of his students that has gone away to college. No heartache!
Karini mo Renai
A collection of stories: - A Temporary Lover - a man asks his reluctant crush to date him as a trial for 2 months - There was another one but I forget what it was - A man who can't hold down a relationship with women cleans his senpai's apartment and wishes they could date instead
Hajishirazu Na Yoru
A series of stories. Lightning pace. The first story was my favorite, a young man and the priest who helped to raise him while his mother was sick.
Koori Ga Tokeru No O Matteru
The sweetest story was about a man who found a lost boy who turned out to be a ghost.

Multiple stories, including one about a boy who had been in love with his best friend so did what he could to keep girls away from him in high school, and asks for one night together for memories.
Hitorijime no Jouken
A series of one-shots featuring super hot characters, especially the last two.
3-manen no Kareshi
Chapters 1-4: A man sick of relationships with no future rents a professional boyfriend but ends up falling for him.
Henshokuka no Kawaii Akuma
A surprisingly sweet collection of stories about demons who survive on human dreams. Maybe it's the dog sleep music I have in the background, but third story was actually quite moving.
Toki no Maigo o Sagashite!
