A Tsundere Cohabitation with My Arrogant Childhood Friend (MIDV-524) for 5 Days Moonlit Night

I have a childhood friend who's younger than me. Our parents are good friends, and when they went on a five-day trip together, they left my friend in my care. She seems aloof, but she's afraid to sleep alone, so she crawls into my bed. She's also afraid to be alone in the bathroom, so she shyly wears a swimsuit and takes a mixed bath with me. I'm constantly teased by Hinano, who, despite her strong and proud nature, isn't unpleasant. She's proud yet does lewd things to me—is this the opposite of kindness?! This is a subjective portrayal of our tsundere cohabitation life.
