What's the end of the lingering resentment?

The ending of The Best of Us is that Huai Yu gave up the opportunity to study in a foreign university because of his mother's illness. Later, he worked hard to study for a doctorate, but he gave up the hard-won opportunity for further study because of his mother's relapse. I visited my mother in the hospital and learned about Huai Yu's experience in the past ten years. I can't be calm for a long time.

After leaving the hospital, she exchanged messages with Huai Yu, saying that she would accompany Huai Yu to tide over the difficulties. Huai Yu was deeply moved and went to the highlands to see her in late autumn. The two men smiled at each other and said nothing.

Huai Yu's role experience:

Huai Yu doesn't belong to the gifted "learning god", but he took part in the physics competition with his love for physics. However, due to the psychological imbalance in the competition, I didn't do well in the senior high school entrance examination, and I was only admitted to Class 5 of Zhenhua Middle School. Huai Yu is an out-and-out scholar, but he is partial to certain subjects. He never recited Chinese when studying with Sheng Huainan, but took his Sudoku out in class.

Unlike Huai Yu, who never fails in major events, Huai Yu may belong to the kind of "unlucky" who fails in important exams. Huai Yu didn't do well in the college entrance examination, so he went to an experimental middle school in a neighboring city to repeat it. He refused to contact everyone, including his heart, and even changed his number. After a year's repetition, Huai Yu finally got his wish and was admitted to Tsinghua with the third place in the college entrance examination for the second time.

But at the same time, Huai Yu's mother suffered from uremia. My father had to continue working abroad to pay huge medical expenses, and Huai Yu had to give up Tsinghua to take care of his mother and study in a local university. He studied hard, completed all the credits in three years, got a full scholarship to study in the United States, and shared it with Yang Lin and his wife in the United States. Seven years after graduating from high school (in the play 10), Huai Yu went home to visit her mother in the summer vacation, only to see her again.
