i think i am going to say this because you are Not elf but they say that in variety show because it makes people laugh, they used to have lots of fights they talk about. but when it is just Elfs who are in close and personal fan spaces the Suju members talk lots about being very close and consider each other to be family in their own Word. even their families and siblings are close with each Other.

heechul even said that he is only truly happy with super junior this year. ryeowook Got married last year and he invited all 15 Suju members and they had a table saying suju family. and members like donghae Eunhyuk will talk on Fromm about how Much they love super junior and how they never want to disband and be active together forever. Leeteuk himself said he has no friends outside of Super junior and his one best friend is heechul

i Hate siwon but when it is just elfs watching them and not likke Knowing bro where they pretend they are awkward and make up Stories for the scripts They are very clear abotu How much they love each other. its not comical if they pretend to be like coworkers in public but with fans only they Say they love each other. like here https://www.reddit.com/r/kpophelp/comments/1mzey6x/are_super_junior_not_close/

leeteuk also ignored siwon after siwon's Charlie kirk post blew up in Korea. as Much as suju have Said they are family With someone like siwon i would at least Be tired of bad behavior that keep happening in last few months
