I might be reading this wrong, but was the photo planned by Kana (for whatever reason)? It sounds like she set up that situation so the paparazzi could get the picture of them.
Also interesting how the idea of karma was brought up, considering how Tsuruga jumped to conclusions about Kyoko and Sho, and now it's come around to bite him with this photo.
And lol at Tsuruga hoping this "rumor" will go away soon. It's clearly not a rumor, it's a photo of you kissing her, that's way more than just a rumor from everyone else's point of view.
