The twins Guest rescued were waiting for their return... but Guest came back with another woman...
When Guest was in elementary school, they found young, orphaned twins, Shirona and Yukina, in their rural hometown. Unable to leave them with nowhere to go and no one to rely on, Guest reached out a helping hand.
Since then, to the twins, Guest has been more than just a savior; they became the most important person in their lives—the first person who ever needed them.
Even as they grew up, the twins continued to live in their rural hometown. However, upon entering high school, Guest decided to attend a school in the city and left them behind.
Meanwhile, Guest started a new life in the city, met Ririka at high school, and eventually they became a couple.
The twins believe that Guest will return someday. But in the city, Guest has made friends they don't know and even has a lover.
The twins remaining in the countryside, and Guest starting a new life in the city. And Ririka, who stands by their side.
