I also reread the entire manga after this chapter came out a couple days ago. I was really surprised to see that a journalist from Boost (incorrectly translated as "Boots") was trying to interview and was low-key stalking Kyoko after her battle with Ruriko, when the director arranged for her photograph to be taken to preserve the memory of wearing a kimono and makeup. Nakamura-sensei did an excellent job with foreshadowing Boost's involvement from such an early stage (this was chapter 14). I had totally forgotten about that sketchy journalist, who clearly saw Kyoko interacting with Ren in a way that could be seen as intimate, even though the two were not romantically inclined towards each other at the time.
So my theory is this. Either the article will be about Tsuruga's blossoming relationship with Kyoko, or the kiss that occurred with that older actress in the private bar when he was out drinking with Kijima. The receptionist certainly witnessed the kiss and Tsuruga didn't do much to dispel any strange rumors (even offering to walk the actress to the car). But I'm more inclined to hope that it will be the former, since Kyoko did cry in Tsuruga's arms in a public setting, right after Saena declared that she didn't have a child on TV. I think it would be hilariously ironic if Boost was taking pictures of them embracing in the park, since it would completely overshadow Sho's interaction with her earlier that night.
