Infamous playboy Tristan Romero meets ordinary Lily at a lavish ball, and arrogantly predicts that she will wake up the following morning between his designer silk sheets! Powerless to resist this wicked billionaire, Lily knows Tristan is only offering one night. But then she discovers she's pregnant, and Tristan's aristocratic duty demands he take Lily as his bride.

Lily's shame over accepting a loveless proposal is heightened when she realises that, as the Spaniard's wife, she'll be expected to fulfil his every need.
