Male protagonist: Lu Jibai (alias Zishang) Female protagonist: Ning Wangshu (alias Xian'a)
A drunk accident made Ning Wangshu pregnant with Lu Jibai's child. He placed her in an apartment and took good care of her. The relationship between the two gradually warmed up but their affection was not revealed.
At the New Year's Day banquet, Ning Wangshu argued about his life experience and learned the identity of his biological mother.
After six years, they finally reunited six years later. Ning Wangshu mistakenly believed the old news about his marriage to Ning Zhiyu and had long given up thinking about it. Fortunately, Ning Zhiyu and his wife clarified their misunderstanding, and Lu Ji confessed his eighteen years of affection and regret.
After the reunion, Ning Wangshu refused to return to his old home, and Ning's father finally revealed his deep fatherly love, and all regrets were finally fulfilled.
