My Tsundere Cohabitation Life with My Arrogant Classmate - Nanazawa Mia MIDE-605

I have a childhood friend who's younger than me. Our parents were so close that when they went on a trip together, they left my friend, Nanazawa Mia, in my care. She'd be afraid to be alone and would crawl into my bed, and she was so shy that she'd wear her school swimsuit to the mixed-gender bath, allowing me to have my way with her!
