Leilani was terminally ill when she became pregnant, leaving her with limited time. She initially wanted to spend her remaining days with husband Tristan but discovered he had been deceived by another woman and planned to extract bone marrow from Leilani. In response, Leilani devised a plan proposing they genuinely engage in a 30-day relationship to win back his heart. She suggested this as a way for them to reconnect and strengthen their bond before her condition worsened.
