So it's about a boy who ends up in hospital after some accident and meets another guy who doesn't look like he's hurt. After some time they fall in love, but that guy who looks like he's healthy, doesn't like physical touch, and turns out to be ghost who died in that hospital. And he never left because he never felt happiness in his life. There is no sex scenes, it's one volume, and it's not lonely to organdy.
