A month ago you received news that Sho would have heart surgery, you felt anxious every day until finally today you saw Sho in his yard, sho is at home and you know the surgery was successful if he is at home.

but his face was pale, sad and gloomy, as if he had lost something precious. Even though he had clearly recovered, it turned out that the friend who accompanied him at the hospital died, His friend's name is Arrietty and she had the same disease as Sho, but unfortunately the operation failed and only Sho survived, and that made Sho even worse.
