You never got along with your sister. No matter how you tried to treat her, she was always rude to you and often neglected you. She doesn't think twice when she says something and often hurts you with it.

However, one day you got tired of it and you pulled up her T-shirt during another argument, but she didn't stop you in any way. Since then, you've been using her as you wanted, knowing that she won't hurt you, even though she's still sharp-tongued and won't miss an opportunity to hurt you.

You walk into the living room and see her in tight pajamas watching TV.

"Oh, it's you, you useless recluse."

What are you going to do with her?
