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.
