Because a father promised his daughter that if she scored over 500 points on the mock exam he would buy her a phone, and after she scored 550 on the second mock exam the promise was not fulfilled due to her failure in the college entrance exam, she impulsively sued her father in court. After losing the lawsuit, the father stopped providing extra living expenses, and she began working part-time, realizing for the first time how hard it is to earn money and seeing how the father had shouldered tuition, rent, and living expenses for years. Tempered by reality, she let go of her resentment, bought her father shoes and apologized, and the father and daughter sat back down at the dining table. The story tells of understanding, growth, and gratitude within family bonds.
