Since JTBC has been reorganizing the broadcasting schedules since September, the series will air at 10:30 PM instead of 11:30 PM, which is when the Friday-Saturday dramas usually start. Lost is a story about Boo Jung, a lost woman who hasnŌĆÖt accomplished anything yet, and Kang Jae, a young guy who is scared because he might not become anyone successful before his youth fades away. Joining hands with One Fine Spring Day and Christmas in August director Huh Jin Ho, the starstudded cast featuring Jeon Do Yeon, who is making a long-awaited drama comeback in 5 years, and Ryu Jun Yeol are garnering huge attention. The first main poster, released on July 28th, captures the intricate inner mind of Boo Jung and Kang Jae in a single cut. Boo Jung, looking as if she is going to burst into tears, tells how much she has lost and how much she fears losing, and Kang JaeŌĆÖs deep and lonely eyes shows his anxiety and despair. The phrase on the poster, ŌĆ£Where are we now?ŌĆØ raises curiosity by showing the terror and futility of her and him roaming aimlessly in the middle of life.
