One member you'd want as your sister

I would definitely want SeoHyun as my older sister because she is extremely dignified, poised, demure, calm, intelligent, beautiful, well behaved, and very much mannered. She is very insightful as well. I'd feel as though with her being my unni, then she'd guide my feet in the right path and teach me the rights and wrongs of the world. I don't have an older sister at all, and I feel as though she'd be a great older sister because of the way that she acts and she'd be a great influence on me, actually. <3
