その着せ替え人形は恋をする (그 비스크 돌은 사랑을 한다)

Traumatized by a childhood incident with a friend who took exception to his love of traditional dolls, doll-artisan hopeful Gojou Wakana passes his days as a loner, finding solace in the home ec room at his high school. To Wakana, people like beautiful Kitagawa Marin, a trendy girl who's 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 Wakana's wounded heart be able to handle the invasion from this sexy alien?!
