This was a really sweet story. The blonde, who i believe is the seme, was dating someone but found out they were cheating. The seme is working a job at a bath house (i believe) and there he meets the man in charge, the dark haired uke. The seme learns that the uke has a friend he has had a one sided crush on for a long time now. That said friend is getting married. The seme likes the uke but the feelings seem to not be returned.
Blue! Blue! Blue!
