Sweet & Sour

“Did you think it would stay sweet forever? Then why is it so sour?”

Lee Jang-hyuk (Jang Ki-yong) and Jung Da-eun (Chae Soo-bin) agree to keep going when new opportunities pull them toward a long-distance relationship. Lee Kae-byeok, adapting Kurumi Inui's novel Initiation Love, follows them through the calls and visits, a first love stretched across the miles. Each new chance asks more of them, and the relationship has to survive it.
