High school student Wakana Gojou spends his days perfecting the art of making hina dolls, hoping to eventually reach his grandfather's level of expertise. While his fellow teenagers busy themselves with pop culture, Gojou finds bliss in sewing clothes for his dolls. Nonetheless, he goes to great lengths to keep his unique hobby a secret, as he believes that he would be ridiculed were it revealed. Enter Marin Kitagawa, an extraordinarily pretty girl whose confidence and poise are in stark contrast to Gojou's meekness. It would defy common sense for the friendless Gojou to mix with the likes of Kitagawa, who is always surrounded by her peers. However, the unimaginable happens when Kitagawa discovers Gojou's prowess with a sewing machine and brightly confesses to him about her own hobby: cosplay. Because her sewing skills are pitiable, she decides to enlist his help. As Gojou and Kitagawa work together on one cosplay outfit after another, they cannot help but grow close—even though their lives are worlds apart. Traumatized by a childhood incident with a friend who took exception to his love of traditional dolls, doll-artisan hopeful Wakana Gojou passes his days as a loner, finding solace in the home ec room at his high school. To Wakana, people like beautiful Marin Kitagawa, a trendy girl whos always surrounded by a throng of friends, is practically an alien from another world. But when cheerful Marin—never one to be shy—spots Wakana sewing away one day after school, she barges in with the aim of roping her quiet classmate into her secret hobby: cosplay! Will Wakanas wounded heart be able to handle the invasion from this sexy alien?!
