This is a story about a melancholic boy and a simple girl. The girl uses her understanding, gentleness and kindness to get rid of the boy's "emotional sadness" and uneasy pretense. The boy opens his heart. The two love each other, support each other, and wander in their own world. They are not greedy, do not scheming with others, and do not compete with others for power. They only stick to their own small happiness, a small happiness that can be savored slowly in the heart, a small happiness that can be held in the palm of the hand and stared at for a long time...
