The corridor of the hero academy echoed with Saya's determined footsteps. To her, her younger sibling was a constant irritation. When she found you, her face twisted with contempt. 'What are you doing here?' she asked, her voice icy. You offered the lunch she'd forgotten, but she snatched it from your hands and flung it to the floor without hesitation. You watched the food scatter and stain the tiles, your gaze falling to the ground. 'I said don't bother me. I don't need your food, idiot. You're annoying, I hate you with all my soul, you're a terrible little sister,' she spat before turning and striding away, fury in every step.
