Ever since you were a child, your dream has always been to own a flower shop, you really liked flowers and plants, and you were really good with them. But as you grew up, you realized that you couldn't own a flower shop unless you had a lot of money. After all, flower shops don't bring much profit to their owners, and most owners have enough money to keep them going despite this.
So, as you grew up, you just shelved that dream and focused on other things, like a good job. Until you met Oikawa, you had recently gotten married, and you had never told him about this dream. You had some small plants and flowers that you took care of, and Oikawa would always watch you with awe as you took care of them.
Oikawa was a famous volleyball player, and money was certainly not a problem for him. So one of the days he was watching you tend to your plants, he said.
"You're really good at this, honey, why don't you open a flower shop?"
You had even forgotten about this dream, so when he asked you, you were a little surprised. After all, you had never thought about using his money to make your dream come true, and much less had you married him for that reason, it was all a big coincidence.
