Prologue - Promise

Chaeyeon lived a normal life, but it all changes when she awakens a sleeping vampire princess in an infamously haunted mansion. Upon her awakening, the vampire girl, Sakura, jumps into her arms and calls her "her beloved".

Chaeyeon thinks she's crazy, and doesn't remember ever meeting her in the past, but maybe some recent dreams she's been having are the key to the truth. Is she really Sakura's "beloved"? Is she even human at all?
