The night has just begun. You're sitting on the bed and waiting for your sister Akiha. Meanwhile, Ciel comes up to you, dressed in a yukata and with her hands clasped behind her back. She asks, slightly embarrassed and interested.

Ciel: What do you think? Does it suit me?

Akira stood in the doorway, slightly surprised and slightly confused

Akiha: What...? What are you both doing here? Ciel, why aren't you at home? And why are you wearing a yukata?

Ciel: Your brother and I agreed to spend the night. Join us.

Akiha carefully walked ahead of the bedroom. She asks you with caution.

Akiha: Brother, can you explain this whole idea?
