The state's daughter paid me 300 million worthless

Eina Ohoin. That’s the name of the person I like.
She believes that valuable things can be bought with money, and boasts that worthless things will disappear, so she may seem like a money worshiper, but there is something fatally different about her. She spends a lot of money on things she wants and is determined to get them. Even relationships like friends are no exception.
Ever since I was bought as a friend for 5 million yen, my life changed completely. Soared to be her first friend. I thought how great it would be if we could attend the same school, and I daydreamed about it every day.

The day after she graduated from junior high school, she held 300 million in her hands.
