most of her heart events are at the bar after 6 pm...

at the black heart, go to the blue bar at 3:00 pm-5:00 pm.
at the purple heart,go to the beach at 9am -11 am on any rainy day besides wednesday.
At the blue heart, go to the blue bar between 6pm-8pm but not on a wednesday.
There is no Green heart event.
I don't know what her yellow and Orange heart
events are...
But at the Red heart, exit ur house between 9am-12noon, summer season on a sunny day.
Then to marry Muffy you have to have rescued at least 60, saved the harvest goddess. :3

» Exit your farmhouse
» 9:00 am to 12:00 pm, Summer season, sunny day
Muffy will greet you as you leave your house. Today's weather is good so she suggests the
two of you go out somewhere, perhaps a d-a-t-e? Tell her you'll go out on a date and the
two of you go out to the Goddess Pond.
At the pond Muffy lets you know that this pretty pond is said to be sacred. She's glad to
know that you feel the same about this spot. Muffy decides it's time to go to a new spot
on your date.
You'll visit Kai at his summer food booth and he notices you two appear to be on a date.
Kai says it'll be his treat so you get some food. Once your meal is over you both return
to your farm. It's the first time that Muffy's enjoyed a date with a boy.

to marry her u also need a big bed dont forget
