Zhang Yue, a Chinese student studying abroad who transcends classes and is proficient in Korean, carefully planned to get close to Wu Renyu, a son of a wealthy family. An accident left Wu Renyu temporarily blind. Zhang Yue opened his heart with gentle care. However, just when the relationship was about to become clear, Wu Renyu completely forgot about her due to brain trauma.
Guan Nali, a Korean girl who has always had a crush on Wu Renyu, quietly took Zhang Yue's place by virtue of her fluent Chinese and convenient location. Fate turned around: After returning to China, Zhang Yue and Guan Nali actually became close friends because of their language resonance in a foreign cafe, unaware that each other's lives had already been intertwined.
When Zhang Yue was preparing hard to enter the bank controlled by the Wu family, the examiner sitting in the interview seat was none other than Wu Renyu - and the new assistant beside him was her "good friend" Guan Nali, whom she talked about everything. Under the white veil of memory, stolen emotions and replaced lives will all be repaid at the moment when the truth is torn apart.
Zhang Yue finally understood: once you step on some stairs, you can never look back. As for the huge gamble of love, she had already lost everything - unless he could think of the trembling tenderness when the gauze curtain brushed against his palm.
