Lin Lina is a very ordinary girl, with no shining point in her body. Like many girls her age, she loves fantasy. She has someone she likes but doesn't dare to say it out loud. It's just a secret crush. She hated her own mediocrity, wanted to be different, and wanted others to notice her, so she secretly made changes. She felt that she had changed but others still didn't notice her. She was very disappointed and didn't understand why, but as she continued to grow, she discovered that changing for others would only make her less like herself. Change from the heart is the real change. She understood this truth and changed for herself. In the end, she discovered that she had worked so hard to change in order to get the people she liked to notice her, but now she changed not for anyone but for herself, but she had attracted people who really liked her.
