Hatsukoi Fuzen Moratorium

About this title

Tetsuya, a college student, lost the Japanese doll that his grandfather had cherished when he was young, and has been searching for it for more than 10 years. By chance Tetsuya met Saku, a guy with a face that looks just like the doll, and proposes Saku to meet his grandfather together. (Source: Enterbrain, translated)
