The Yukimura family moved next door to Mitsuki's family. Although Mrs. Yukimura came to visit when they first moved in, Mitsuki did not meet their new neighbors for some reasons. Until an ordinary weekend, she met the youngest son of the Yukimura family through a window, and then gained a little boy, a companion on the road to growth, and a confidant.
Mitsuki: Seiichi shines when he works hard for his goals. This high-spirited fighting spirit inspires me unconsciously. I want to be such a person too.
Jingshi: Because of Mitsuki's company, I am not alone on this road to my dream and can go on firmly. Mitsuki's power is beyond imagination.
Mission: Strive hard, never give up, and meet at the top
