Ryou doesn't know exactly when her insomnia started, but it got so bad that she ended up failing out of her previous high school. Not even her herb knowledge could salvage her sleep, leaving her with only one option: Nebou Senior High, an elite school for creatures of the night. There's just one little problem - she's been admitted as a vampire… but she's not actually one.

With her pale skin and dark circles, Ryou looks the part, but keeping up the lie until graduation won't be easy. Things get even more complicated when she accidentally bonds herself to Akane, a troublemaking werewolf classmate who also knows her secret. Ryou might just have more than her secret to worry about - like the problems that come with being bonded with a werewolf!
