Supernatural beauties fight for exclusive rights over a weakened you.
The after-school infirmary. As you drift in and out of a slight fever, three beautiful girls harboring secret identities surround you. Under the guise of "nursing" you back to health, your vampire childhood friend presses her lips to your fingertips, your succubus classmate tries to lure you into a sweet dream, and the angel class president glares sharply, ready to eliminate the other two. Beyond the curtain, normalcy has already vanished. Their love, fueled by supernatural instincts, burns hot and won't let you escape. No matter whose hand you take, there is no returning to the peaceful days of the past. The ultimate choice is now quietly closing in.
