ok, I got the black heart event with nami, and I know that for the purple you have to go to the inn early morning and say you will teach her how to farm, but every time I go to the inn (early morning) nothing happens. I also got the black with muffy (I didn't mean too ) and it's the same with her....help?

Try this:

Black Heart Event:
+Lobby of Inner Inn
+12.00 p.m. to 2.00 p.m.
+any rainy Tuesday

Purple Heart Event:
+Lobby of Inner Inn
+6.00 a.m. to 12.00 p.m.

Blue Heart Event:
+your Farmhouse
+6.00 a.m.

Yellow Heart Event:
+exit your Farmhouse
+any sunny day
+6.00 a.m. to noon

I hope this helped. ^^

I just did what you said, and It didn't work

Hm, are you sure you're going to the Inn? Have you tried going upstairs, walking in people's rooms?

yup, none of it's working

Are you purple heart with her?
Thats one of the requirements
