A tsundere living together with a cheeky childhood friend for five days

I have a younger childhood friend. My parents were well-known, and I ended up taking care of my childhood friend Mia for five days when the parents of both families went on a trip. I got into my bed because I was afraid of sleeping alone, and I went to the bath in a school swimsuit because I was afraid of turning my eyes off and it was embarrassing. I'm always at the mercy of Mia, who is cheeky but I can't hate! It's a turning point to doing naughty things while still being throbbing! ?
