It’s the summer of 2009 and Cheong Ah is a senior in high school who is the second of three daughters. Her parents run a small chicken restaurant while her older sister is a news anchor. Cheong Ah doesn’t have any hopes or dreams, and no one knows why, except for a friend she has only talked to via text messages. She skips school and gets on a train to go meet him where she runs into a handsome soldier.
