On the first day of high school, Yun Xian met an outrageous class teacher - a reborn genius who had lost his memory. All the teachers in the school knew about his incredible academic skills, but he himself was in a state of confusion: one day, he sat in front of Yun Xian and made fun as a "classmate", and then suddenly awakened as a teacher and went to the stage to give lectures with a piece of chalk. The birthday girl in the front row looked at the happy couple, but Unzen, who was the most aesthetically scumbag in the class, relied on his modern thinking to never care about the teacher's "stupid" complaints. Instead, he flirted with her intimately time and time again, making the arrogant man feel young and sentimental in his heart. An anti-routine multiplication problem became the key. He suddenly remembered his identity and went straight to the stage to write and solve the problem, recognizing his identity as the class teacher in public. But this innocent pull was finally broken, and the genius teacher suddenly disappeared. The teachers had long tried to persuade him not to get too close to Yun Xian, but it was still in vain. With no way out, all the teachers and students in the school forced Yun Xian to find the missing genius teacher who made an exception for her.
