If I ever shipped OHSHC this would be the ship. Kyoua was so evident in happened. He knew what Grandmother was up to with her lawyer. He was actually mad at Tamaki's father's coup because he believed that Tamaki would eventually bring his grandmother around. The flight to the airport to see Tamaki's mother was mostly Kyoua's doing except for Renge's navy. HIs grand schemes on Haruhi and Tamaki's behalf were something to behold. You had the feeling that he was doing it for Haruhi because she loved Tamaki and he was willing to do whatever she wanted to make her happy. Even the date was engineered by Kyoua since they could not depend on Tamaki not to screw things up.
