The episode ends with the bridge scene from the beginning. The man (Jung-woo, now a detective) reaches the woman (Joy/Zoe) just as she lets go of the railing. He grabs her hand and whispers: “Lee Soo-yeon… I’ve been looking for you for 15 years.” She turns her head slowly — tears in her eyes — and the episode ends on her shocked face.
The child actors' performances are widely considered some of the best in K-drama history.
