Grey Gcn means a new girlfriend. I dont knos if he has a new girlfriend. Since Xiao Hu sid that i got the time wrong, the colors will change if use Alex's convert to the chinese date, since in Ny is one day later than CHina. So all the colors will be wrong. The the color for Gcn will be white, and that means sick girlfriend. But he has not girlfriend, so it can also mean girl friend, good female friend?

it means his secret young lover
