Synopsis
Han Jeongun hadn't thought about Goo Seonho in ten years. Then a man appeared at his door — tall enough that Jeongun had to look up to meet his eyes. "Hyung, it's me. Seonho." The ten-year-old boy whose head had barely reached his shoulders was gone. He had come back to keep a promise, three months before Jeongun's wedding to someone else. "You said when I turned twenty, we'd get married and become a real family."
