Moonbin answered, "Usually me and my dongseng fool around. To be honest, I wasn't a caring oppa, but after debuting and watching my sister prepare (for debut), I think I automatically took on the role. I know it's going to be harder for her compared to what I went through. My dongseng probably has a lot more on her shoulders because she's under a (big) label and since she's a girl. I want to tell my dongseng to cheer up."
