There was an ancient male protagonist who was weak and seemed to have asthma. When the female protagonist saw him coughing in the palace, she gave him a handkerchief. The male protagonist's mother (who seemed to be a princess) knew about this handkerchief and arranged for him to marry the female protagonist. The male protagonist did not want to drag the female protagonist down, so he wanted to break off the engagement. The female protagonist pretended to be sad and jumped into the lake. The male protagonist was very anxious and regretted it. He also wanted to jump into the lake. He did not want to break off the engagement. The female protagonist came out of the water. The female protagonist had also read many medical books for the male protagonist's illness.
