Actually if Ray's wingman and friend, Stephen, didn't come along, Akiko would have choosen Ray. It was actually a semi-love triangle between the 3. Stephen and Ray both had a thing for Akiko (Ray being silent about it). Stephen made the move first. Ray, being the good friend and wingman, decided to not persue the relationship with Akiko and remained friends. Akiko knew Ray was in love with her but she also knew what could happen between the 2 if Ray said something about that relationship. And the relationship between Akiko and Stephen was heading toward marriage. I don't think I need to go any further.
Really, there never was the question about Ray.
