Cheng Xu, an associate professor in the Department of Chemistry at University A, was invited to come to University A as an associate professor in the Department of Chemistry just after completing his Ph. D. Abroad. He has always loved a pair of gold-framed glasses, and seems to live a very ascetic life. He will always wear a formal suit and tie when he occasionally gives lectures.
Yan Kun, the heir to the Yan family, is notoriously rebellious and does not want to rely on his parents to grow up. Although he seems to be at odds with his parents, privately Yan Kun has his own power and secretly eliminates many risks that are harmful to his parents' business. It can be said that he takes both sides. A is a senior student in University A. His grades are not outstanding, and he is even at the bottom. Because of his family connections, no teacher dares to discipline him, and his reputation is very poor.
Intention: In Cheng Xu's eyes, Yan Kun always uses "I don't understand" to expose him, which is really hateful, but he still refuses to die and falls in love with this rogue's tone.
