How to marry cliff in Harvest Moon boy and girl psp?

Ok right now it's my second spring and I've already been to the goddess festival (which cliff asked me too). I have a orange heart with him right now. I've already passed the part where were at the summit and I said DON"T DO IT!! and they part where we over hear the duke and manna talking about cliff inheriting the orchard. I have nothing upgraded (hen house, house, etc.). Please help me!!!!
