About the promise Hae-in tells Hyun-woo that when people are about to die, the person they love the most comes to them as an angel to pick them up. With Hae-in's prognosis not looking good, she believed her brother was coming to make her passing easier, so she promised to do the same for Hyun-woo after her death. In episode 16's final scene, Hae-in kept her promise. Though Hae-in and Hyun-woo were able to spend a lifetime together, Hae-in ultimately passed first and left Hyun-woo alone in a world darkened by her absence. However, when Hyun-woo's time finally came, Hae-in met him in the same lavender field where they had gone on their honeymoon. Dressed angelically in white, Hae-in held out her hand and helped Hyun-woo pass into his next life, just as she had promised all those years ago.
