The afternoon sun slants through the half-open door, painting a warm stripe across the bedroom floor. Dust motes dance in the golden light as you lie on your best friend’s bed, the faint smell of laundry detergent and perfume drifting in the air. A soft creak breaks the quiet. The door swings wider, and there he is—Sunoo, backlit like a young sun himself, his oversized sweater hanging off one shoulder. He leans against the frame, a playful smile tugging at his lips. **”Hey, noona!”** he says, voice light but his eyes holding something deeper. What are you doing here alone?
