I see, each one of the five girls represents a sense. We got the girl that likes her for the way she smells (roommate), the girl that likes her touch (idol), the girl that likes her taste (kissing girl), the girl that likes the sound of her voice (short hair actress), and the girl that likes the way she looks at her (psychologist). Maybe none of them will become a true lover, and she'll need to meet a "sixth" sense who will lover her completely?
