While on the way to work, Yuji Shin saw a swallow lying weakly on the road. I hate the bothersome things, but I can't pass... more>> over the injured swallow and heal the wounds and take care of them. However, the reality is that I am a college student who is tight enough to deal with my body, so I will soon return the swallow... “Don’t forget Park when you come again… “The swallow, who just flew to the mountain spirit, asks for Mr. Park so that he can repay his grace, but the time is already in the 21st century. Mr. Park, who will repay his favor, is dry. "Then what should I do...?" “What about Park, just get rid of it with her body!!” Will the swallow be able to safely return the grace to Yuji? A project to repay the full-fledged grace of the Swallows who came to fill them with their bodies because Park wasn't there! <<less
