The life of Lin Yue, a lonely and somewhat insecure boy, changes dramatically after he becomes a magical girl. He learns that he will fall in love with his own brother, Ye Yuan, in the future. Though he tries with all his might to prevent that future, he still finds himself developing feelings for his brother that go beyond friendship. Before he can face his feelings, however, another woman comes between them, plunging Lin Yue's love life into a huge crisis.
Note: This is a gender-bender story, not pure romance and not one-on-one. It's told from Lin Yue's perspective and is aimed at a niche audience.
