Ningyou no Ie

Naoki found out that he had a crush on Ryusei Hagiwara, the atelier of a famous and successful doll-making shop. Being the neighbor of Ryusei's older brother, Naoki decided that Ryusei thought nothing more of their relationship. They just knew each other through Ryusei's older brother. Although Naoki hung around Ryusei often, there was one room in the house that he was forbidden to enter. Of course, Naoki couldn't stand the thought of not knowing Ryusei's secret. Determined, he set himself on entering the room to find out what was up. What Naoki didn't expect, however, was to find a human-size doll that... looked like him? (Source: MU)
