I guess you have to spend money to get the flower, right~

Slurp! Don't worry, you can get plenty of flowers even without spending money. Utilizing in-game missions or your friends' fields is a wise approach. With a benevolent heart, may I ask which missions you are primarily undertaking right now?

I got flowers in-game without spending money.
