Good things start secretly. We are ready to call "secretly" a good state. We are not sure, but can't let it go. After taking the first step secretly, good things happen one after another. The concept of gift box is derived from the custom of "thief when enjoying the moon" in Japan's Mid-Autumn Festival. In Japan, children are seen moon' messengers. They can shuttle from household to household and steal offerings in the Mid-Autumn day. The households which are stolen also regarded the behaviour as a good sign. But, adults never steal offerings, they only steal hearts.
