Igarashi Yui (Masataka Kubota) is a medical radiologist. Previously, Yui was invited to participate in a project to develop software to assist in reading images using artificial intelligence. Yui decided to go to the United States and bid farewell to her companions. Two years later, Yui returned to Japan, hoping to return to Ganchun General Hospital. However, the new director, Haijima Masahiro (Takashima Masahiro), rationalized the hospital and no longer needed radiologists. All work was outsourced to the imaging center. The companions of the year also transferred to other hospitals. One day, violinist Marin Hosou fainted at a solo concert, and Haijima, who was sitting in the audience, rushed her to Ganchun Hospital. At the same time, Ganchun An (Honda Tsubasa), who no longer worked at Ganchun Hospital, finished her work and set off on her way home. She met the pregnant Morishako Yumi (Mori Hirokazu) who was in unbearable abdominal pain. At this time, Yui appeared. @哦撸马
