Normally Asahi Kuromine can't keep secrets, lie, or prevent others from guessing what he's actually thinking. When Asahi tries to confess to the mysterious and pretty Youko Shiragami, who he secretly likes, he accidentally discovers her secret, she’s a vampire and now replaces one secret with another. If this gets revealed Youko has to leave the school and disappear from his life forever, so Asahi must now do the impossible . . . actually keep a secret. Youko isn’t the only one as there’s other students also hiding a secret Asahi will discover as well.
