My Dress-Up Darling

Wakana Gojo is a high school student who secretly admires hina dolls and wants to follow in his grandfather's footsteps as an artisan. He had isolated himself from everyone because of the social damage he had experienced because of his interest. He bumps into his classmate Marin Kitagawa while using a sewing machine to create a doll's costume one day at school. Marin requests Wakana's assistance in making cosplays after appreciating and praising his doll and his artistic endeavors. Wakana first worries that he won't be able to make Marin a cosplay costume because his skill is restricted to Hina dolls. But he decides to carry it out.
