Before leaving, the swallow asks him to remember "Park," hoping to repay his kindness. The swallow then flies away, heading toward the mountain spirit. However, the swallow's request is complicated by the fact that it is in the 21st century, and the person it seeks, Mr. Park, is not available. Frustrated, the swallow suggests using "Park" as a way to settle the debt. The story follows the swallow's efforts to find a way to properly repay Yuji for his help.
