Tamayura no Dinette

Kagaya wakes up in an unfamilar atelier, having no memory of who he is, and with a leash attached to his neck held by a strange man dressed in lolita garb. The man, Dinette, introduces himself as the owner of the place, and of Kagaya as well, claiming that Kagaya is his beloved "doll" that he hides from the world to protect him.
