Department store

I bought three books, my cousin bought toys, and my young sister bought same toys as cousin. My grandmother said to them, why you guys were buying these unnecessary things? They said because I need it and they want to play with those toys. My grandmother said do it yourself, finally they bought their toys.
Finally, my grandmother, she spent money total 70,000 won.

Poor grandmother, how poor she is?
However I don’t think I have to change this book to money. Later, at grandmother house, I spent all the time to read this new book. It was fun and I will buy another one because this book is publishing a novel with in a serial form. I will buy 3 more serial form about this book!
