[Reducing Mosaic]MIDA-456 Arrogant childhood friend and underclassman's 5-day tsundere cohabitation life Shunkai Eto

I have a younger childhood friend. Our parents are close too, and while both sets of parents go on a five-day trip, I'm taking care of my childhood friend, Ayanaga. Despite her cold attitude, she comes into my bed because she's scared to sleep alone. She also says she's scared and embarrassed to take a bath alone, so she comes in wearing a swimsuit. She's feisty and bratty, but I can't hate Tsunetsune Saienaga. She always messes with me! Being tsuntsun while doing lewd things is just the reverse of her affection! Tsundere cohabitation life sent in first-person perspective!
