Su Jiameng falls into a huge misunderstanding, deeply misunderstood by the Gu Chengli she deeply loves, and suffers from long-term cold treatment. It was actually her who stepped forward to save Gu Chengli back then, but this past event was usurped and claimed by someone else. She pours her sincere heart into Gu Chengli, sacrifices a lot for him, and even bears their child, but all she gets is a continuous stream of estrangement and suspicion. Successive changes make her lose her reliance, swallowing many grievances alone. As past events are gradually clarified, all misunderstandings dissipate like smoke. Su Jiameng's love has long been exhausted in the lengthy alienation, and she resolves to completely let go of the past.
