Lin Yuchen, who was called to teach, wanted to ask a doctor to help him prove that he was exempt from masturbation. He was in good health and was originally going to be rejected by the doctor. In a moment of desperation, he had to say that his sexual desire was too strong and he might not have masturbated for a long time. The female doctor was frightened by Yuchen's amazing size and couldn't help but have a closer relationship.
