Winter 19/ alt. Winter 21
Won the traveling merchant moves into Mineral Town a few days after you arrive at the farm. He takes up residence in Zack's house on Mineral Beach. His shop sells different plant seeds than what Jeff sells at his store.
If you raise your friendship with Won, he will allow you to sell items to his shop, and even play an Apple mini-game where you can earn prizes. The only difference between Won and the other bachelors is his heart-color is invisible. You will also have to own the Flower Vase and see 3 other events before Won will accept your Blue Feather.
You don't get any say in the matter when it comes to Won's shop. He's going to keep it open and not even consult you on it. When you get up in the morning he will have already left for Zack's house. He won't even give you a family discount on his items! Won will return home at 6:00 pm every day.
On the Spring Thanksgiving event you'll still receive gifts from the unwed bachelors at your front door in the morning. Won will also come by once a season and offer to sell you one of his special apples.
