I have read one Manga before it is one shot and nake up a whole different story in each chapter. In chapter 1 I think, there is a couple that on his boyfriend's birthday, he went out bought a cake, but it is raining that day, he was able to save a child, but he couldn't save himself and die. His spirit is always next to him, and in the end, the other person suicide
So it is only one chapters. And I think it have another one shot by another authors. (Not sure). It is BL manga, where Uke saved a child during a raining days, and he died. That raining days is Seme birthday. The seme decided to suicide after one or two years. The spirit uke keep talking to seme, but the seme never see him.

I have look for this manga, but couldn't find it
