Wow! Now the box is full of something. What's in the box ?
Hearts!!! Lots of hearts. All my hearts are belonging to my Ling.
And what's this ? Hearts with Wings. Flying hearts!!! That's all my hearts flying to my Ling's heart.
When Ling open my hearts, each of the hearts are crafted with some saying with Ling keep smilling looking at it :P
