The university student, Yuuki, is a ghost painter who paints pictures on behalf of his father, who is a famous painter.

One day, a beautiful vampire youth named Leo appears.

Carrying a sad past, Leo wants to kill himself.
While Yuuki is attracted to him, he could only paint his pictures.

Eventually, providing a kiss as a substitute for blood gradually escalated...

With a youth who has lost his "color" and an immortal vampire who is desperate to die, each day is sad but vivid.
