My Dress-Up Darling

Wakana Gojo is a high school boy who wants to become a kashirashi--a master craftsman who makes traditional Japanese Hina dolls. Though he's gung-ho about the craft, he knows nothing about the latest trends and has a hard time fitting in with his class. The popular kids--especially one girl, Marin Kitagawa--seem like they live in a completely different world. That all changes one day, when she shares an unexpected secret with him, and their completely different worlds collide
