MIDV-524 Living together for five days with a conceited childhood friend and junior, Tsundere-style. Moon Cloud Night

I have a younger childhood friend. Our parents are close, and while they're on a five-day trip, I'm in charge of looking after my childhood friend Yoru. She acts cold but comes into my bed because she's scared to sleep alone, and she even takes baths with me wearing her swimsuit because she's afraid and embarrassed to bathe alone. She's feisty and insolent, but there's no way I can hate Yoru! Is she doing lewd things while acting cold because it's her way of showing affection? A subjective view of our tsundere cohabitation life!
