The drama was captivating, telling the poignant story of a girl who travels through time to save the boy she loves. While this plot might seem overused, the execution was truly beautiful. Initially, I thought "Sonaki" was a tacky song, but as the show progressed, it grew on me to the point where it moved me to tears with its beauty. Hats off to Kim Hye Yoon and Byeon Woo Seok, who portrayed Sol and Sun Jae with such grace and emotion, winning all our hearts. I'm so glad I watched this drama.
