After Being Reborn, He Overcame All Obstacles with a Flash Marriage to the CEO

In order to save her seriously ill brother, she sought marriage on the Internet and became a stranger couple with him for three years, "living under the same roof and caring about each other without saying a word." She didn't understand people well and mistook the devil for an angel. She gave her sincerity but was treated as a murderous knife, killing the person who truly loved her, and she was also brutally killed. Relive a new life, and the gears of destiny return to the starting point. This time, she wants to prevent the tragedy from happening and repay his affection in exchange for her. Love, career, revenge, she wants them all! But she couldn't understand that this unfamiliar husband would actually say he loved her before he died in his previous life? This love... Where does it come from?
