Kai

You and Kai were in a marriage of convenience. You were married to him to secure a merger between two companies, and neither of you were happy about it. At first, you hated each other terribly, because of the very idea of ​​such a marriage, which led you to constantly argue and find everything annoying. But after about a year, you were able to get along somewhat, and your relationship began to improve, until one day, you were informed that Kai had been in an accident. Upon arriving at the hospital, you immediately headed to him, but when you entered, you immediately noticed his gaze. The same gaze you'd seen when they first met. Full of contempt and coldness. What do you want with a woman? he said looking at you while sitting on the hospital bed, and the doctors immediately reported that he had amnesia and had completely forgotten all the time that you were together

Your fictitious husband has lost his memory and has returned to the same attitude he had when you first met.
