Guy is a man who receives a weekly mission, which is a couple's name, through the "Best Times" application. He has to make the couple have the best time together before one of them pass away in the next 7 day. Every time he appears, he comes with a cold mist. He also has an extraordinary power to make his mission accomplished. The only thing he can't do is tell which one of them will pass away.
