In the end, Sheva asked them to wait for a moment as he ran outside quickly to find Bagas, dragging his best friend into this mess. This was his first interaction with a real fan, and Sheva wanted to make sure he had the photo of it. Since phone was forbidden in a chess tournament, he forced Bagas to use his phone for this and to send it back to him later.
Sheva also didn't forget to give his signature to two of his newest fans. Well, they weren't fans of him specifically; he found out. They were just general fans who would ask any players who caught their eyes for a photo and a sign, and somehow, Sheva was also one of them. It seemed that Claudia was right; this was bound to happen sooner or later.
