When Alice wakes up, a strange woman is standing in front of her. Her name is Kasumi. She apparently carried Alice, who was drunk and passed out, back to her house. Kasumi, a university student, is attracted to Alice, who uploads videos of herself to a website and lives her life doing what she loves, and she begins to visit Alice's room almost every day. And then she has her first confession, her first kiss, her first cunnilingus... The moment when a girl falls in love with another girl comes suddenly one day.
