Hetalia X Mermaid!reader: A strange man

You finally got to the human land. It was quite a long trip and you're exhausted. This swimming gonna lost you a few weights, not quite a bad thing. The beach that you reached was beautiful but quiet with beautiful white sand. And the view is just great.

Now I have to find somewhere to turn myself human and blend in. You thought, looking over the rocks to find a perfect secure spot, near the water of course (since you can't walk currently). You crawled over there and casted the spell over yourself as fast as you can in case someone decided to go sightseeing here. A bright light surrounded you and your shiny tail turned into human feet. You wiggled your toes to check them and try walking. It's a bit new so you tripped quite a lot. After that you put on some clothes your mother somehow have of the human world.
This is gonna take a while to get used to. You whined mentally.

Luckily, someone came after you finished dressing and not before that. He was quite a...girly man, with long hair pulled into a ponytail. He wore clothes that looks different from the clothes you wear. Thinking back, the men you saw on the ship had different clothes too. You were surprised, you didn't think there were so many kind of human(Author: or country, )
"Nihao-aru! What are you doing here so late?" The man greeted you.
"W-well, hello. I'm just came here." You said
"Oh, a newcomer then! Welcome to the town!" He smiled "Well then, do you have a place to stay at?"
"Oh, no I'm not. Well, do you know one I could stay in?" You asked
"Of course I do! As a bonus, it could be a both a house to stay in and a shop. What do you say?"
"W-Wait! A whole house?!! But sir, I don't have that much money."
"That's why I said the house can also be a shop. You can both have some savings and a place to stay. Many benefits for you, isn't it?" Quite a silver tongue he got there
"Oh, ok. I think I'll take it. Since It's late and all."
"Very good. My name is Yao by the way. It will be totally 9000xxxxxxx$ for the cost of the house."
"WHAT!!!!!!!!!!!"
