After the Flash Marriage, the Boss Always Fell in Love with Me at First Sight

I couldn't stand it after reading three chapters. Spoilers (little rant) The heroine seems not too strong? Her grandfather's will was that she could inherit the family property once she got married, and then she went on a blind date desperately to find someone to marry her. She has a sixth uncle who wants to compete with her for inheritance rights, and we don't know where her other uncles and aunts are. Then her sixth uncle's people roped in a fish seller (the male protagonist) and asked her to marry him, so she asked him if he wanted to marry her, and he agreed. Then she took him back to the mansion and said that she wanted to get married by agreement. Both the male protagonist and I felt that her move was disrespectful. She also said that the agreement was because she was afraid that she would die (her hair would turn white due to a strange disease) so that he could benefit? When she dies, doesn't the male inherit the marital property? The man was knocked unconscious by her and tied up. When he woke up, he didn't know whether he had amnesia or had traveled through time.

Come on, it has been collected hehehe
