What is the main story of Hu Shi's "Lifetime Events"?

One-act play. The heroine Tian Yamei had a free relationship with Mr. Chen when she was studying in Japan. After returning to China, she hoped that her family would support her in marrying Mr. Chen. Her mother, Mrs. Tian, ??thought that this would be a lifelong event for her daughter. She didn't know whether they would be happy after getting married. Because she couldn't make up her mind and believed in superstition, she went to Guanyin Temple to ask for a fortune from Guanyin Bodhisattva. Unexpectedly, she got a fortune. The poem said: "Husband and wife are determined in their previous lives, so don't force marriage. Misfortune will eventually come, and the marriage will never end." Mrs. Tian was still not sure, so she asked a fortune teller at home to arrange the marriage for Ms. Tian and Mr. Chen behind her husband's back. The fortune teller said that their "horoscope" matched what the fortune teller said: "Snake matches tiger, male conquers female. Pig matches monkey, no end." Mrs. Tian saw that the fortune teller's statement had the same meaning as Guanyin Bodhisattva's poem. , thinking it was God's will, so he disagreed with his daughter's marriage. Tian Yamei said that it was superstition and that we should not believe it but ourselves, but Mrs. Tian was stubborn and firmly opposed. Ms. Tian Yamei had no choice but to pin her hopes on her "enlightened" father, Mr. Tian, ??because Mr. Tian had always been firmly against superstition and would always take her side in any disputes at home. After Mr. Tian came back, he heard Mrs. Tian talking about his daughter's marriage and fortune telling. He was very angry and blamed her for being superstitious. He severely criticized Mrs. Tian. Ms. Tian Yamei couldn't help but feel proud after hearing her father's words. But unexpectedly, Mr. Tian also opposed her marriage later. His basis was "Chinese customs and rules" and "ancestral rules set by ancestors" - people with the same surname cannot marry. Because the surnames Tian and Chen were from the same family 2,500 years ago, they cannot marry in the same family. Tian Yamei thought this statement was unreasonable, but her father refused to listen. She also proposed to change her surname from Tian to Shen, just like her father's workaround, but Mr. Tian disagreed. In the end, Ms. Tian Yamei resolutely decided on her own life-long events, leaving a note saying that her children should make their own decisions about their life-long events, and ran away from home in Mr. Chen's car.
