In G.R.E.Y.'s study of humanity, he has learned that they seem to be at their best when they share, give, and help others. However, it seemed illogical that giving makes you happier than receiving a gift yourself. So G.R.E.Y. tested this by giving a gift to his friend, R.E.D. (Robotic Emotive Darling).
You may not see it on their faces, but seeing her positively thrilled overloaded G.R.E.Y.'s circuits with happiness. Ahh, the joy of giving. :]
@domenicododaro - Hahaha oh boy...for some reason your comment made me think about 50 Shades of G.R.E.Y. Anyhoo, I think G.R.E.Y. is a bit smitten by his new friend. He'll have to analyze this thing called "love" at a later date.
@jyokota - Weeeeeeellll...not quite. I'm gonna admit my secret to you Junko. I couldn't find R.E.D. anywhere. I actually merged two photos of G.R.E.Y. together and did some extensive editing to make him look just as I remembered her. Guess you could say this is artificially love for G.R.E.Y. until we find her. :P
