I'm not someone who knows how to name novels.
Diarmuid's neighbor, Kenneth, was abandoned.
People who didn't have many interactions with each other, because of an accident, their lives infiltrated into each other.
Diarmuid, who had no good impression of Kenneth at first, learned about Kenneth's past and developed subtle feelings for him during his contact with Kenneth.
It's a short article, and I'll finish it when I get to a reasonable point, because I have a feeling that I won't be able to stop being ridiculous later on.
