Su Yaoyu has a normal IQ and a high emotional intelligence. She is the illegitimate daughter of Su Mu, the campus wonder at that time. When Su Yaoyu was 3 years old, Su Mu adopted his friend's 5-year-old son Xia Lie (Xia's only son) who died in an accident and renamed him Su Fufeng. In junior high school, Su Fufeng met a close friend (Ke Ting, the future heir to the American business empire Prancer). Su Yaoyu skipped a grade and entered the third grade of junior high school, Su Fufeng's class. The feelings between the three people are constantly being resolved and confused. Due to various reasons such as family and education, Su Fufeng and Su Yaoyu gradually drifted apart despite knowing each other and cherishing each other. Ke Ting's existence gave Su Yaoyu the longest warmth, and his indifference, wisdom, and persistence deeply moved Su Yaoyu. However, youth is a fresh scar. Although the years are peaceful, things and people have changed after all. Only the heart knows that time is not forgiving.
