My No. 1 treasure is my happy childhood memory. I only have this treasure and a medical book that my maternal grandfather recorded and left while I was alive. Like me, I will have pure childhood memories of the object of longing in the minds of modern people. I hope that my work will be able to take out the precious memories in my heart and many people, free from tired daily life, find my own freedom, and help with mental stability and healing. With this mindset, I began to capture this treasure-like childhood memory in one space.
