I honestly love when the boys support each other. Like with Yongguk when he had to go on his hiatus and all the boys would assure us that he's alright. I mean, besides the absolute shitshow that they are without him, they did pretty well.
Then there's also whenever one of them is crying, they comfort him by making fun of him. The videos are Zelo's letter to his parents and then Daehyun and Youngjae making fun of him for it, all in good fun. My brother would always do the same whenever I cried in an effort to cheer me up. That's how you know that the members are more than just bandmates, they're family.
