I have a younger childhood friend. Since our parents are close, I ended up taking care of her, Hikari, for five days while they were on a trip. She came into my bed because she was scared of thunder, and she even joined the mixed bath wearing a swimsuit because she was afraid and embarrassed to be alone. Even though she's always teasing me and acting arrogant, I can't help but be captivated by her. Her tsundere behavior while being intimate feels like a sign of affection! Get ready for a tsundere cohabitation life, captured from a first-person perspective!
