I recommend this book of mine. I really put a lot of thought into it. I've always believed that imprisonment is not only the confinement of the body, but also the invisible oppression of the mind and spirit.
At first, Jian Lina used what she called love to imprison herself by Lu Ming'en's side. Later, the arrival of Li Nanguo showed her what love was supposed to be like.
To avenge the Li family, who had destroyed her own family, Jian Lina accepted Lu Ming'en's help and got close to Li Nanguo, the only son of the Li family. But as they spent time together, she realized there was more to the story and decided Li Nanguo should not be blamed. Just as she was about to walk away, she discovered that Lu Ming'en had tricked her: he had been using her to take revenge on the Li family.
