I have a childhood friend who is younger than me. Our parents get along well, so I've decided to look after my childhood friend Mia for five days while both of our parents are away on a trip. She gets into my bed because she's afraid to sleep alone, and she's afraid to close her eyes in the bath and is embarrassed, so she bathes with me in her school swimsuit. Mia is cheeky, but you can't hate her, and she keeps toying with me! Is her naughty behavior while acting tough a sign of her affection? A subjective video of a tsundere cohabitation life!
