A Love in 100 Days

After a tragic accident, spirited young woman Ria finds herself transformed into an angel, assigned the identification number 5623. Despite her new celestial existence, she remains deeply connected to her past life, particularly her memories of her beloved boyfriend Ban Ji Hwan from her time on Earth. When Ria discovers that Ji Hwan's name appears on a mysterious list, she becomes determined to protect him from an unknown fate. Through divine intervention, she's granted a chance to return to the mortal world, but there's a catch - she must inhabit the body of Hae So, a shy and reserved high school girl whose personality is the complete opposite of Ria's bold and outgoing nature. Now living as Hae So, Ria must navigate the challenges of high school life while keeping her true identity hidden. She faces pressure from family dynamics, school bullies, and the difficult task of reconnecting with Ji Hwan without revealing who she really is. As she struggles to adapt to her borrowed life, Ria discovers that protecting those we love sometimes requires more than just good intentions - it demands understanding, patience, and the courage to face unexpected truths. This touching story explores themes of love, sacrifice, and second chances as Ria learns what it truly means to care for someone, even when everything has changed.
