I'm not really familiar with Korean honorifics culture and so on. It's clearly that TXT call BTS as 'hyung' in private, but in formal occasions especially in front of camera, it changes into 'sunbaenim'. Is that something like unwritten rules?
I remember how Yeonjun being sulky on vlive because Hyuka keep calling him 'Yeonjunsshi' instead hyung, and he said "there're only moa and us in here."
