Dont remember much of the manga Im looking for. But one of the guys is playing other people on their money (kinde of) and the other one is an office worker. Later in the manga an old school friend to the office worker comes by and whant him to invest in something (dont remember what). So he asks the other guy to play his "secretary". To see if the old school friend's trying to play him off his money. Which he is. So the "secretary" decides to play the old school friend of his money instead.

Hope it helps. Really whant to read this manga again!
And its yaoi.
