He already show concerned when stumbling upon it but clearly move on after asked if he will go back home or not. Might won't even mentioned it again since he doesn't seems to have any attachment to home nor it is the main plot of the story. Even if his friend who search his whereabouts suddenly appears to take him back I doubt he will agree to comeback since I don't remember he ever try to find way back by himself lol
He needs to be more concerned with the shrine. Idk, his lack of interest in it concerns me lol
