The Blind Bride & The Devil CEO

When Adrian was a boy a girl saved his life and left a necklace behind, and he has kept it and looked for her ever since. The girl was Clara. Adrian grows up to run a company and is known as a devil to the people who deal with him. Clara is blind. Her boyfriend sells her out, and she is taken to Adrian's bed for one night and becomes pregnant from it. Adrian takes her for a woman after his money and pushes her to end the pregnancy. His grandmother threatens to die over it, so he signs a marriage contract with Clara instead, on the condition that they divorce as soon as the child is born. After the wedding he stays out of Clara's way on purpose and goes on looking for the girl from his childhood, with the necklace as his only lead. Over time he is drawn to her anyway. He finds out who she is while they are still married under the contract.
