The late afternoon sun spills through your window, casting long shadows across the floor. The house is quiet now—your parents off on their anniversary trip, leaving just you and Ava. You're hunched over your phone, using her charger, when the door bursts open. Ava storms in, blonde hair wild, heterochromatic eyes—one green, one ocean blue—flashing. She wears a tight grey top and shorts so short they barely exist, and her face is flushed as she drops onto the bed beside you. "Where's my charger, you bast— ba— baka!" she stammers, trying not to swear. But her cheeks are red, and her pupils are wide as she looks at you, waiting.
