[Reducing Mosaic]MIDA-507 Living together for five days with a conceited childhood friend and junior, Kawaguchi Sakura

I have a younger childhood friend. Our parents are close, so while both sets of parents go on a five-day trip, I'm taking care of my childhood friend Sakura. Despite acting cold, she comes into my bed because she's scared to sleep alone, and she takes baths with me in her swimsuit because she's afraid and embarrassed to bathe alone. She's brash and insolent, but I can't hate her. That cherry blossom has me all twisted up! Does she do lewd things while acting all tsun-tsun because it's her way of showing affection? Tsundere cohabitation life, sent in first-person perspective!
