Diabolik Lovers: Stay Beside Me

"Who are you?"
"Who am I to be here?"
Alice Rose Mirusaki, a girl who had been seperated from her father when her father says that he'll be going out for a "buisness trip" and promised her that he'll come back for her. Her father sent her to a mansion where her father's "very close friend" lives and will take care of her for her father. But for Alice, all of this seemed strange and she has a bad feeling about this. She didn't know anything about her father's close friend and she even heard rumors about the mansion that there are demons living in the mansion from other people when she's being driven there by her car driver. Will she be living there until her father comes back for her? How long will she be waiting? Who will be expecting her in the mansion?
