I think Pope and Nadech both have clean images because yeah I think they are very honest with their fans. Nadech doesn’t have an IG, the only thing public about Nadech is his Koojin status everyone is obsessed with. His mother shows his life through her IG while Pope shows little of his family but he has an IG to share. Both men are normal citizens despite the immense popularity but when a fan thinks of a celebrity I believe a lot assume they have this ugly persona. They both do a good job at staying true to themselves which makes fans love them even more.
Also, Nadech doesn’t entirely have a clean image, some of his jokes suggest otherwise lol plus his farting...lol!
