Heart-wrenching story of a man who is afraid to hold back the one he loves, and a man who loses his memory but not his feelings. Not as emotional as Mou Ichido, Nando Demo (http://www.mangago.me/read-manga/mou_ichido_nando_demo/), but definitely worth the read. The man with amnesia, Shizuka, can't explain his feelings for his customer Sakai (Yukihiko), and slowly attempts to bond with him. He soon discovers they were lovers and his memory returns :)
