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 Sakura for five days while both of our 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 in her school swimsuit because she's scared and embarrassed to be alone. Sakura is competitive and cheeky, but she's hard to hate, and I'm constantly at her mercy! She's always acting mean, but she's also doing naughty things...
