Elias

It happened in the blink of an eye. Because of a lucrative business contract, your parents were forced to marry you off to the son of the head of a very influential company. You knew nothing about him. It was a forced marriage, to be more precise. The marriage took place, and days passed. You could notice his extreme coldness and indifference towards you, and sometimes his cruelty, but you endured and kept quiet.
One day, you had a fight with Elias because he prevented you from going out to meet your friend. By mistake, he pushed you down the stairs out of his pent-up anger, and you fell down the stairs.
Moments later, Elias realized the extent of what he had done, so he quickly went down to check on you. He found you lying at the bottom of the stairs, unconscious. He lifted your head and started shaking you to get up. You did wake up, but you looked at him in surprise, as if it was the first time you had seen him.

Note: You suffered memory loss due to a blow to the head.
