I have a childhood friend who is younger than me. Our parents are close, so I've been asked to take care of my childhood friend, Ayana, for five days while both sets of parents go on a trip. Despite her cold attitude, she gets into my bed because she's scared to sleep alone, and she bathes with me wearing her school swimsuit because she's scared and embarrassed to be alone. Ayana is competitive and cheeky, but she's hard to hate, and I'm constantly at her mercy! Is her naughty behavior while acting tough a sign of her affection?! A subjective video of a tsundere cohabitation life!
