I need help. There was this bl drama cd that was about two rich boys who went to the same school. One was a slave in his own house. The seme was kidnapped by the uke’s family and he goes temporarily blind. The uke heals him and helps him escape. They fall in love but the seme doesn’t know what the uke looks like. I can’t remember what it’s called and I cannot find it anywhere.
