I have a young childhood friend. Our parents are on good terms, and during a five-day trip when both sets of parents were away, I left my childhood friend, Hikaru, with me. She's terrified of Rai, so she'll come into my bed, or be afraid to be alone in the bathroom, so she'll shyly wear a swimsuit and bathe with me. Hikaru always acts like a shy little doll to me, yet I'm constantly playing with her. Is her haughty act of doing erotic things the opposite of kindness? This is a subjective portrayal of our tsundere cohabitation.
