Who Is the Substitute for Whom?

[Double cleanliness + misplaced substitute + misplaced secret love + love at first sight + chasing wife in the crematorium + HE] At a masquerade ball five years ago, Ye Xiyuan and Xi Yunting fell in love with each other at first sight, but they did not know each other's identity. Ye Xiyuan was not supposed to appear at the dance. Tang Yuwan hired Ye Xiyuan to pretend to be her in order to mess up this party, which was actually a blind date. Because the two looked very similar, wearing masks could make the fake look real. Unexpectedly, Xi Yunting fell in love with Tang Yuwan disguised as Ye Xiyuan. But something unexpected happened before the pursuit could begin, and Xi Yunting needed to be hospitalized for a craniotomy. After the operation, Tang Yuwan went abroad. Five years later, Ye Xiyuan and Xi Yunting met again, and the familiar feeling brought them closer unconsciously. But Xi Yunting always thought that it was Tang Yuwan at the dance, and the irritable and irritable sequelae of Xi Yunting's craniotomy operation made Ye Xiyuan feel that it was impossible for him to be the same person. However, even though both of them knew that the other person was not the Bai Yueguang in their hearts, they still couldn't control their instinctive reactions.
