Harvest Moon: A Wonderful Life Special Edition Tips

Get Muffy Easily
What i did was i barely talked to her at all. (aside from a few Moon ores) When I got the Blue feather i gave it to a couple girls (including her) and the all said no. Then in the middle of summer, I awoke to find her at my bedside saying something like "Why didnt u give this me this feather? u know how I feel about you" Then you can either Propose to her, or kick her out. u propose, she accepts, ur all happy.

I guess the bottom line is, give the feather to other girls, and she gets jealous.
