So, Jing Yuan has been staying in the hospital all along. Jing Xiaonan paid her a visit now and then. However, every time he wanted to ask her something, Jing Peng would cut him off. This happened a few times, and Jing Xiaonan stopped trying to converse.
Since Jing Peng mentioned it last time, Mrs. Jing hadn't visited Jing Yuan in front of him anymore. She only came when he was away.
Only then did Jing Yuan find out that she was not the biological daughter of Mrs. Jing. No wonder she had never been loved by her. It turned out that she and her second brother, they were half-siblings, sharing the same father. Somehow, it's better than being full siblings and having an incestuous relationship.
Jing Yuan comforted herself. She knew she was only fooling herself. No matter if they were full siblings or half, their incestuous relationship was still incestuous, and once known, she could be executed by public condemnation.
