On stage, Xiumin has to portray a witty and adorable image because that is his role. Off the stage, he is completely the big brother with a mature thinking and mindset. He is serious and calm, he doesn’t really participate in the craziness along with his dongsaengs. He doesn’t voluntarily step forward to showcase himself, doesn’t fight doesn’t snatch for the chance to. He doesn’t even really approach people on his own. His age and personality might have played a part in the maturity and responsibility in him.❤
