I returned to my hometown after winning the koi lottery.

It was clearly designed by the God of Wealth, so why is it called a "Love System"?! Little Peach was a bit confused. She'd won the lottery without even realizing it; it wasn't because she was so lucky, but because the unlucky God of Wealth, who had been demoted, had put in a lot of effort to send this lucky koi fish home to reunite with her family.
