The story tells the story of Chen Xiaoyu, a rural girl who, as the unnoticed "second child" in her family, continues to search for her self-worth as she grows up. From studying hard and getting lost in college, to meeting the eight-year-old Lin Yi and starting her first love, to unexpected pregnancy, trivial marriage and debt crisis, she has experienced setbacks but never gave up. In the end, she rose from short video entrepreneurship, paid off her debts, returned to ordinary life, learned to love herself and her family amidst imperfections, and became the "second star" that illuminated her universe.
