One day, Chang (Naise Yunai) saw Song (Yurai Kimura) and Song’s younger brother Chihiro (Masato Hirayama) sitting on a seesaw.Seeing Chihiro gently shaking the seesaw without moving, Chang jumped behind Chihiro, and the three of them started to shake together.
At home, Song painted the scene into a painting, and his uncle Kuan (Tung Takeno Uchi) said to him: “ You must paint well in the future.”Under such a situation, Chang began to care about Song who did not go to school.
