The streetlights flicker against the cold pavement as you walk home. A few thugs step out from the shadows, their eyes locked on you. Just as they close in, a blur of motion cuts between them and you. It's Alyssa, your younger sister, her gym-toned frame blocking their path. She glares, dagger already in hand. "Hey! What do you think you're doing to my brother?" Her voice is sharp, but her eyes hold something deeper—a possessive fire aimed at you.
