100-il Sarang

Ria, now an angel assigned number 5623, continues to remember her past life, especially Ban Ji Hwan, her former boyfriend. A year later, she accidentally sees Ji Hwan's name listed in an e-book that predicts who will die within 100 days. She prays to the angels to help save him. To do this, Ria takes on the identity of Hae So, a shy and unassuming girl, a stark contrast to her usual self. Hae So lives in a difficult situation, dealing with a chaotic and stressful home life, including bullying from her half-siblings. Ria resolves to go through everything to be close to Ji Hwan again. However, she soon discovers that Ji Hwan no longer recognizes her.
