Love, In the Nick of Time

When they first met, he was a little beggar and she was a girl from a rich family. A simple donation made him remember it for ten years! When we met again, he was the high-ranking president of the group, and she was a low-status cripple employee. A substitute marriage established an indescribable relationship! But he didn't realize that the person he had been looking for was right next to his pillow... She didn't know that the person she had always hated and despised was that boy! Until the situation changed and he learned the truth and wanted to redeem himself, an accident separated the two people again... Is it fate or evil?
