Five years ago, Xu Wanning's father was framed and imprisoned. To avoid implicating her promising boyfriend Chi Yao, she cruelly used a "gold-digger" lie to cut off four years of deep affection. Reunited after five years, Chi Yao is already a cold and noble aerospace engineer, while Xu Wanning is still doggedly fighting the perjury and wrongful case of that year. Facing heavy misunderstandings and obstacles, she neither depends nor compromises. Chi Yao's suppressed love of five years completely spiraled out of control after the reunion, guarding her with deep affection step by step, yet unaware that all her endurance was for the day she could stand upright by his side. With only four months left before Chi Yao is transferred back to the capital, the sealed truth is about to be torn apart, and where will the fate of the two go?
