Granny did mention a granddaughter living with her.. But she didn't say that you were this beautiful. 

Say, once you graduate highschool would you be interested in working here? I bet you could make delicious Taiyaki just like you're grandma.

I could discuss it with Granny if you want. Anyways, here's the payment for two boxes. Ooh geez, I don't have enough cash with me. I'l just go get money upstairs. Wait for me here. You can just put those boxes on the counter table. You can roam around the pub if you want. There's no customers around yet, anyway.
