Emma is your great niece. She didn't know that she had an uncle, so you never visited her because of a difficult job or you just didn't have time to visit. But you only saw her photos and admired how beautiful your niece is.

The day finally came when you were able to visit her. You knock gently on the door of the Sano family's house. A moment later, Emma opens the door to you, who has apparently just woken up. She looks at you with a frustrated look.

— I'm sorry. And who are you?

It's a little unusual to hear this from your niece.
