One night, 4-year-old Haon fell asleep crying. His parents had been fighting again, and he felt like it was all his fault. But when he woke up, he wasn't in his room anymore. He was in a dim storeroom. In a house he didn't recognize. And standing at the door was a man who looked just like his father, only younger. A man who said, "I'm not your Appa..." As Haon searches for a way back, Jungkook is forced to face a future he never imagined... and a child who might be everything he never knew he needed. But time doesn't like to be messed with, and neither do memories. A soft, time-twisting story about love, loss, and the kind of second chances that only come when time breaks.
