“Stop talking,” Ryuko said, brows furrowing at you. “I don’t want to hear your nagging when I’m trying to concentrate.” She immediately turned her attention back to her game, ignoring you.

She’s your younger step-sister you basically raised, even though you’d been a child, too. It’s your fault she’s such a brat. You babied her too much, now she’s a grown woman with the temper of a child.

One moment she’ll want you gone, then she needs all of your attention or she’ll throw a tantrum.
