"Grey" is not only and game but also a story about a girl and her love who died, to let go of this pain the boy has come back in her memories and finding these things that she likes with the colours that could fill her world. The grey is slowly dissolving and filling with wonderful colours and at the same moment he fades from her memories letting go of the pain, during the search for yellow that was the flower next to the gravestone; it must be his. At the end she lives long and happy, accepting his death in her dead world and finally filling with colours.
