That sudden "CHILL" panel kinda highlights that despite all his assurances (to others, but also to himself) that he's completely fine with Urumin getting more fans, there must be a part of Kimiya (a hidden part, even from himself, based on his reaction on the next panel) that is very,
very protective of his fandom. Not just of Urumin, but his fandom of her. Should make the next chapter/s quite interesting.
I'm also looking forward to seeing how Urumin is further reacting to her sudden fame/infamy.
