My Dress-Up Darling Vol 1

by Shinichi Fukuda

Wakana Gojou is a fifteen year old high-school boy who was socially traumatized in the past due to his passion for dolls and doll-making. That incident left a mark on him that made him into a social recluse. But one day he was caught talking to his doll by Kitagawa Marin, a sociable gyaru who is perfectly open about her otaku interests -- in short, the complete opposite of him.

Instead of making fun of him, she's amazed by his skill on the sewing machine, and asks if he'll help her make a cosplay! Through sharing their passions, they end up in an odd but supportive relationship.
