Sheng Shuran woke up in a foreign hotel and dreamed of an ambiguous night with her adoptive brother Chi Xuan. A call came from China saying that Chi Yan had a car accident and she was anxious to return home. She didn't know that this was a trick by the other party. After returning to China, Chi Xan frequently got close to her for various reasons, and behaved beyond the standards of a sibling, but still pretended to be envious. Sheng Shuran was ashamed that her feelings for her brother had deteriorated, but she also had trouble controlling herself. In addition, her fiancé Fu Lin didn't seem to treat her sincerely, and she was conflicted. In the end, she discovered that the seemingly innocent Chi Yan had already been determined to win for her.
