Mr. Ling, Please Pet Him Gently.

The man she loved most married her sister, and she even had to marry another seriously ill man in her sister's stead. However, on her wedding day, she was betrayed by the groom, and she faced the embarrassment alone. It was rumored that the man was sick, and he was seriously ill! But who can tell her who the man was who ripped her apart on their wedding night? She thought she had escaped that disgusting home, but she didn't expect to end up in another dragon's den. How should she protect herself?
