Tbf he doesn't think jjk is looking for him or cares about him so it wouldn't really strike him to decline photos.
He must have some suspicion that JK would try to get him back otherwise he wouldn't have blocked him and made sure there's no way for JK to contact him.
But he told them not to mention anything to him than took a picture with them. Even if they didn’t post it or mention anything, a big group photo would likely be posted by his manager or something. Idk just not smart (〜￣△￣)〜
consenting to a photographic evidence of your whereabouts when you are in hiding from a psycho that has been scouring the earth for you is actually so fucking dumb
