In order to save her father, she wanted to send herself to Young Master Gu's bed, but was told afterwards that Young Master Gu did not come to the hotel at all.
Then … Who was the man she had sex with?
Her father had committed suicide in prison, causing her, who had fallen, to almost be sold to a rich Old Man by her uncle's family. When she was at a loss, a strange man appeared, hugging her tightly and claiming to be her fiancé.
She had a new turning point in her life after getting a marriage certificate with an unfamiliar man in a daze.
