I have a childhood friend who is younger than me. Our parents are close, so I've been entrusted with taking care of my childhood friend, Rikka, for five days while both of our parents are away on a trip. Although she has a cold attitude, she gets into my bed because she's afraid to sleep alone, and she takes mixed baths wearing her school swimsuit because she's afraid to close her eyes and is embarrassed. Rikka is cheeky but lovable, 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!
