In high school, Chen Yuanxi's dream of having a young love affair was shattered by Tang Shouyang's words, "It is conservatively expected to fall in love at the age of twenty." She was fully expecting Mr. T to make a surprise confession when he was 20 years old in his sophomore year, but she never expected that Mr. T, 20, would choose to go to the United States for study and exchange. Twenty-four-year-old Chen Yuanxi reunited with Mr. T who had returned to China at his friend's wedding. Will she still start this chaotic war between the two of them? But she didn't expect that the other party had already thought of countless strategies to beat her. This is year after year, I think about it in my heart. I thought it was a chaotic secret love, but when I saw the reality clearly, I stepped out of the fog of youth, only to find that the two were too far apart. I regained my confidence with the intention of ending it. What kind of ending would it be?
