a blue feather
A player has a choice of many girls to marry in the game Harvest Moon Island of Happiness. The player must fulfill the marriage requirements of the choose girl and presenting her with the blue feather. Pierre will compete with you for Natalie's affections.
once you get 7 or 8 hearts for the person you like a few days later it should be on sell at chen's shop
go to Chen's shop and purchase a blue feather, give it to your love and it will trigger the proposal event. But you have to complete the marriage requirements
It depends on what heart color he is on. Try to give him his favorite, porridge, every time he is on the island.
When you have your girl/guy at 10 hearts, experienced all heart events, and have the blue feather from buying it at Chens then you can marry them. Doesn't matter when.
you must have a blue feather and at least 10 hearts
1- you have not completed all heart events (it's alright to say the wrong thing btw) 2- She doesn't have 10 hearts
