Just a tip on golden heart quest - since there's no more quest after completion the golden heart quest, what we can do is:
Notice how you can request the golden heart from friends?? Yes it will be taken away from you if you gift from wall. However, request away and let them sit in your giftbox until you need it.
Collect 30 at a time or whatever amount you need and finish them off by trading with cupid angel (6 items, more worthwhile than the rest)... make sure you have none again in inventory before gifting to friends on wall. That way, you'll get to keep your golden hearts and be able to gift friends freely.Once you have enough V items collected, you can just complete the golden heart quest on the last day of V quest.
Alternatively, you can wait until you have collected all the items for the quest on the right side of wall (esp glass fragments and magic dusts)and then finish off the golden heart quest. (V quest will return yearly same like Full moon quest)
