He and she were brother and sister. She had liked him for ten years. She did not know that they were not biological brother and sister.

This was a complicated plot about identity and family relationships. The female lead might have liked the male lead at first, but she didn't know that the male lead was actually her brother. The male protagonist and the female protagonist's father were related, and the female protagonist's mother also accidentally got pregnant with the male protagonist when she was pregnant with the female protagonist. When the female protagonist was young, her mother left home, leaving her and her brother behind. The female protagonist and her brother often played together, but the female protagonist did not know her brother's identity. As time passed, the female protagonist gradually discovered that she had special feelings for her brother. She began to realize that her brother cared for her differently from her other siblings. The female protagonist began to think about her identity. She didn't know that she was a girl and her brother was like a real boy. As the plot developed, the female protagonist gradually discovered her identity and decided to reveal her brother's identity and find her mother. In the process, the heroine experienced many difficulties and challenges, but she finally found the answer and re-established contact with her brother and mother. This story expressed the importance of identity and family relationships. At the same time, it also revealed the complexity of family structure and the change of inter-generation relationships.
