Just like the real Harvest Moon game there will be a Heart Gauge, to determine how a person feels about you~ It should be too hard to gain trust!
Here's how the heart gauge works:
Black: Stranger / Hate
Purple: Acquaintance / Dislike
Blue: On good terms (Not really friends yet)
Green: Close Friend
Yellow: Best Friend
Easy, right? Giving your potential friend or love interest gifts they like could boost their level for you (just like in the game). Giving them gifts that hate could make them dislike you even more.
There will be a "Point Bank" so you can give them gifts, as well. C:
