Miura Katsuki, a woman working as a contract employee, misses the last train home one night. A handsome young man approaches her and offers a place to stay. He turns out to be Yoshizawa Soufuu, a former student from the calligraphy class she taught ten years ago. Soufuu is no longer the quiet child she once knew; he has become a famous calligrapher and an idol in the calligraphy world. Their reunion sparks a story that weaves together the past and the present. After quitting her class, Soufuu devoted himself entirely to perfecting his craft. He trained relentlessly, rose to fame, and did all of it for one reason: to find Katsuki again. His feelings for her, which began as a childhood crush, have matured into a determined, unwavering love. Katsuki, now an ordinary office worker, is bewildered by his sudden reappearance and the intensity of his devotion. The narrative traces their gradual reconnection against the backdrop of Soufuu's elegant brushwork and the art world that now surrounds him. Central to the story is the question of whether his earnest and long‑held feelings can ever truly reach her heart, and whether a love once written in ink can bridge the distance of a decade.
