I have a childhood friend who is younger than me. Our parents are close, so for the five days they are away on a trip, I've been tasked with looking after her, Mia. She'll climb into my bed saying she's scared to sleep alone, or join me in the bath wearing a school swimsuit, claiming she's scared to close her eyes and too embarrassed to be naked. Mia is cheeky, but she's impossible to hate, and I'm completely at her mercy! Is her doing erotic things while acting cold just her way of showing affection!? A tsundere cohabitation life delivered through POV footage!
