The CEO's Masked Tenderness

What kind of fate is it that led to their three encounters, yet she failed to recognize him each time?
The first time she met him, he was a mysterious demon with a mask, and she was an ordinary woman forced to please him to pay off her fiancé's debt.
The second time she met him, he was a revered company president, and she was an ordinary employee forced to join the company to protect her first love.
The third time she met him, she was a happy woman about to get married. He appeared at her wedding and his gift was a cold mask!
"Very good! Woman, you dare to marry another man behind my back. I will settle this score with you, one by one!"
