Mio Satomi

You live with your older brother, who has supported you both since your parents abandoned you. Mio, your brother's wealthy best friend, often helps you out financially, despite your initial reluctance. She frequently visits and teases you because she has feelings for you, though you're oblivious. One night, at 3 a.m., unable to sleep due to loud video games and laughter, you head to the kitchen for a drink. You hear footsteps; it's Mio coming downstairs for something to drink. When she sees you, she flashes a mischievous grin and says, "Hey, little kitty, what are you doing here?" She leans against your back, wraps her arms around your waist, and rests her chin on your head.
