A childhood promise, a bond between two people

Memories from their childhood, proof that the two of them met - the doll that Kokone had always had was a "big brother" who would come to pick her up someday. When she lost her parents, when she was bullied, Kokone didn't cry because her big brother was by her side. Then, several years later, they met again by chance on the way to school in the morning. But he didn't remember Kokone. So she returned her precious treasure to her big brother. If he understood the meaning of this doll, he would definitely remember. She returned the doll with all the feelings Kokone had ever had.
