High school student Wakana Gojo wants to become a kashirashi—a master craftsman who creates traditional Japanese Hina dolls. Although he is very enthusiastic about this craft, he knows nothing about the latest trends and struggles to fit in at school. The popular kids—especially a girl, Marin Kitagawa—seem to live in a completely different world. Everything changes one day when she shares an unexpected secret with him, and their completely different worlds collide.
