Hirose Michiko (Nanako Matsushima) has lost her passion for teaching, while Guang (Hideaki Takizawa) is strictly required by her mother Jingjing (Hitomi Kuroki) to inherit the hospital family business. The two met for the first time when their lives were in despair. At that time, Michiko only wanted to marry her fiancé to escape everything in school and quit her job as a teacher. At this time, Guang transferred to Michiko's class. Guang was trying to escape the constraints of her mother Jingjing and was very distressed about it. Guang, who seemed to be so pure that she would break at the touch, strongly attracted Michiko, and Guang also had the same feelings for Michiko. At the beginning of their acquaintance, Michiko could only desperately suppress her love because she and Guang were in a teacher-student relationship. However, Guang's unreserved and brave love for Michiko made Michiko no longer able to remain silent, and her doubts and fears were swept away. However, the pressure from all walks of life continued, and their mutual running-in always happened at an inappropriate time. The two experienced many separations and reunions in difficult experiences and environments. Will this shocking teacher-student relationship be recognized by the people around them? Will they finally be happy?
