Yvette, heiress of Queen Group, secretly works as a caregiver and has donated a kidney to Wendell. Her brothers, Sean (a doctor) and Sam (a finance tycoon), confront her, accusing her of hiding something and pressuring her about a possible romance; she insists she's not dating and plans to reveal her identity to Wendell at the right moment. Moments later Wendell calls in panic: his mother has been admitted to Queen Hospital. Yvette must rush back to the ward, leaving her vow and secret under immediate test as the emergency unfolds.
