I've seen a few versions of this story floating around on different platforms, and the ending can get a bit muddy. From what I pieced together, the central conflict revolves around the fake bride, Chen Yuxi, and the aloof CEO, Fu Tingzhou. The typical resolution sees Chen Yuxi's true identity eventually uncovered, but instead of casting her out, Fu Tingzhou realizes he's fallen for her genuine self, not the socialite she was impersonating.
The drama usually wraps with a confrontation with the family who orchestrated the swap, leading to a power shift. Fu Tingzhou publicly acknowledges Chen Yuxi, securing her position and their relationship. It's a classic 'fake relationship turns real' climax where love triumphs over the initial deception, and the villainous relatives get their comeuppance. The final scenes are often a lavish wedding or a pregnancy announcement, cementing their status as the new power couple.
