Xiao Xi is an ordinary college student. After her crush in high school ended, she met Xiao Qiang, an outstanding senior, and the two quickly fell in love. However, under great inner pressure and self-confusion, Xiao Qiang told Xiao Xi the truth. He liked boys, and dating was just an attempt at heterosexuality. He hoped to change himself but failed. Xiao Xi's first love was greatly stimulated, and she fell into long-term pain and was unable to save herself. Her high school crush came to see her. After she refused, she played a contract couple with Xiao Qiang, helping Xiao Qiang hide the fact that he was gay. Finally, after a brief and profound conversation over the winter, Xiaoxi could no longer endure the conflict between her inner world and the outside world, and decided to reflect on herself and completely break away from the past.
