Kimi no Torso wo Tsukuritai

Synopsis

Rito is a shy girl who dreams of a typical high school student romance. Her complex is about her ample breasts. By chance, she meets an art boy named Shibata, who says to her, "I want to make that body," and her youth is set in motion—a pure "sculpture modeling" romantic comedy begins!
