Kang Hyewon and Kim Chaewon doing the best they can in order to protect their happy family.  ForewordBehind that calm face, the old man keep standing. With his hand, caressing the yellow carnations made by the younger kids. His eyes, as if recording the precious moment to be put inside his memories. Hyewon-ah, please be happy. Thats what he said, before leaving the playground after giving his last glance to the beautiful sight of pretty smiles.
