When the heroine was a child, she was traumatized because of the quarrel between her parents. Coupled with a car accident, the heroine became silent and then developed claustrophobia. Growing up, my elder brother protected me and I didn't have many friends. The male protagonist is three years older than the female protagonist. The general storyline is that she was a freshman in high school and he graduated from high school, and she was a freshman and he was a senior. I always miss it, but I don't. He knew everything about her, but it was the university that was really involved. Because someone confessed to her, it almost succeeded. He immediately blended into her life without leaving any trace, and pitifully she thought she had done something wrong. To put it bluntly, it is the process of a big-tailed wolf hunting a rabbit, and the rabbit knows nothing about it.
