Catarina was a young and beautiful scientist who was arranged married with a CEO's son. Her husband was only interested in her as a lab partner rather than a romantic one...

The guilt couldn't take it anymore and then she divorced and married again to a new partner she truly wanted... But who was knowing that the same serious and cold beauty of her ex-husband will chase her back?
