Remember in the SAO background Asuna and Kirito have gone through a lot, and all those shaped their love, that they are a couple who can trust each other with their own life. So this makes the latest update totally off, where Kirito doesn't want to tell Asuna that he is in a secret investigation in FOG for the police, neither before the investigation nor after it. Why?
Given this is a big plot in the game update and maybe even an important step in Asuna's corruption, Kirito's excuse (in fact, Fujino's excuse) for not telling Asuna what he is doing in FOG doesn't make any sense. From the perks we can see how Asuna loves Kirito: She is willing to do anything for him, even sacrificing her life. She is willing to go to the US to be with Kirito if he studies there. This is a very big decision but Asuna agrees at once with no hesitation at all. It makes sense because this is the SAO background. But in the same background, Kirito doesn't want to tell Asuna what he is doing for the police? And this triggers all the next consequences, including Asuna believing that Kirito is visiting the brothel, right after their date and sex? Excuse me?
