Cheerful part-timer Yuu lives the life of an ordinary beta. He works at a bakery and shares an apartment with his secret crush, a kind man named Ren. Yuu doesn't remember anything from before the time he was rescued by Ren six months ago, but Ren seems undisturbed by his unknown past or the fact that every few months Yuu becomes so lethargic Ren has to put him to bed and care for him until the sickness passes. But what secrets could Ren be keeping? Is it possible his gentle, protective roommate knows more about the missing pieces of Yuu's life than Yuu himself?
