[Reducing Mosaic]MIDV-284 Living together for five days with a haughty childhood friend and junior, Reina Miyashita

I have a younger childhood friend. Since our parents are close, I ended up taking care of my childhood friend Reina for the five days they went on a trip. She acts cold but is scared to sleep alone and comes into my bed, or says she's scared and embarrassed to bathe alone so she comes in wearing her swimsuits for mixed bathing. Reina is feisty and bratty but impossible to hate! Is she doing lewd things while acting tsundere as a reverse of her affection? Subjective footage of our tsundere cohabitation life!
