Zhusha is the "canary" carefully tamed by Qin Si. He doesn't allow her to work or make friends, so he can only exist in the world. She choked for a time and tried to escape, but he always caught her. In an accident in the Year of the Horse, Qin Si was seriously injured while protecting her and her life was in danger. Before he fell into coma, he held her hand tightly and said in a mute voice: "Let you go... The files are in the drawer..." She opened it tremblingly. Inside was not a contract to imprison her, but a signed transfer of all her property, and the sentence: "I'm sorry, I only learned to love you like this." The story starts from the "morbid love" with a strong sense of conflict, and deeply explores the core issues of "the ability to love" and "the expression of love." The theme is to depict a very destructive "love" pattern formed due to original trauma or misunderstanding. The love of the male protagonist Qin Si is extremely paranoid and full of control. He "protects" and "owns" in his own twisted way, but in fact it causes harm. The climax of the story is that when the critical moment of life and death comes, his instinctive choice exposes the truth of "love" deep in his heart - not possession, but sacrifice and fulfillment. The transfer letter and apology are proof of his clumsy and tragic love, and also indicate that he may begin to "learn" how to love. The "fierceness" of the Year of the Horse coincides with the hero's character. The theme does not beautify this kind of paranoid love, but tries to show its tragic roots and point to the possibility of redemption: realizing the mistake is the first step, and true love requires learning a healthy way of expression, that is, based on the other person's feelings and happiness, rather than satisfying selfish desires.
