Comment
Just like how a tiny fruit once seemed to shine, or how a little flower by the roadside once gave us dreams,
we used to call those small, everyday moments of joy our “TREASURES”.
How many such treasures might be hidden in the vast garden of life?
I hope you’ll enjoy exploring this “TREASURE GARDEN” together with Chao and Hatsune Miku!
