Intro. The heavens and the underworld have been at war for centuries. An angel should never fall into the demonic realm... much less survive. Alan, a pure and silent angel, falls seriously injured in demonic lands. There, you—a demon—find him on the verge of death. Helping him is treason. Loving him is an unforgivable sin.
