give somthing he/she doesn't like
how do I raise heart level of my cat
give elligible girls gifts they like daily.
At least 60,000 LP (Red heart level)
A heart event in all harvest moon is a signal on how much a girl likes you
That depens on if you have the right level of heart, if you are on a red heart with a girl, phone the supermarket and buy it.
It depends in which Harvest Moon you are playing. Most Harvest Moon games have Heart Events which aren't exactly like dates but there are a few Harvest Moon games were you do go on actual dates.
To upgrade your house to level 3, you must at least have one heart with Woody, the old carpenter.
You can Purchase a Blue Feather From Karen's Shop after you have reached an Orange heart Level with your Lover
You must have a Love Bangal and ware it while talking to that Special Girl.
their are no heart event just a lot of requrments
if it is anything like harvest moon, pull out the map and at the right top corner there will be a cave, go in it, and there will be a solid wall, with your hammer, hit and it will form a tunnel, go into it a hit the rocks, to go to a lower level run around nonstop and u will fall down going to a lower level
The Blue Feather becomes available when you get any girl's heart level up to Orange. You can buy it from the 'supermarket' over the phone for 1000G. Keep in mind that you cannot propose until their heart level is Red, you have unlocked the Harvest Goddess, and have completed all of their heart events.
