They are orphans of the world, with fathers like great trees sheltering them from life's storms, and mothers who always stand by their side. Yet their parents offer them only an empty kind of protection, never able to truly connect with them.

These "Gu Ni" may exist in any corner of the world. They could be found in the home of the world's richest person, or in the home of the world's most pitiful beggar. And Yu Zhe appeared in an ordinary family.
They are also from Duhe... Zudiwuyinsan
