Shiina, a freshman in college, is enjoying a cozy life in Niigata Prefecture dating her coppersmith boyfriend, Shuu. She’s grown used to the rhythmic sound of his hammer, inwardly dubbing him the “smithing nut” for his obsession with hunkering down in the workshop, even on his days off. What she’s not ready for is a sudden proposal out of nowhere! Barely out of high school, is she ready for the next step? And more importantly, can she really hack marrying into a prestigious smithing family?
Following in the footsteps of one’s family is never easy—especially when that family runs a traditional coppersmithing business in rural Japan. This is a tough lesson for Shuu, who must now decide whether to follow the path his father walked or find his own. But that’s not the only thing he must learn. A coppersmith must meet the expectations of their clients—and the clients themselves—something with which the reticent Shuu struggles. Somehow life has become more complicated than simply hammering away on copper. With his loving fiancée Shiina as his anchor, can the smithing nut rise to all the challenges his vocation presents?
What's the natural next step in a relationship before marriage? For Shiina and Shuu, it’s moving into an apartment together! But each up comes with its own down, and the couple is surprised by the roadblocks popping up alongside the conveniences and fun of sharing a cozy abode. This is especially true for Shuu, who has a habit of not voicing his emotions, complaints or otherwise. Can the two of them hold on to their lovestruck bliss and successfully navigate the challenges that come with cohabitation?
Daily life continues for Shuu and Shiina. Shuu trains a new mentor in coppersmithing, Shiina dives into her training to become head clerk of the shop, and the two enjoy the coziness of their home together. But as the days go on, the stoic Shuu struggles to communicate his love and appreciation to Shiina. Then he finds his moment: a romantic couple’s getaway to Sado Island! With everything planned out down to the most intricate of details, Shuu should have this in the bag—but he soon runs into an unexpected problem. Can Shuu still pull this trip together and show Shiina what she really means to him?
