Wow, Sunny's really mature and really nice. In the entertainment world, you don't have some1 taking care of some1 else when they're a newbie like Hyomin like Sunny did. Watching Strong Heart, you hear stories about the struggles of newbies in variety shows. Boom used to tell Suju members on shows to stop taking his airtime, and Sunyeong of Kara used to go on shows only to be ignored the entire time without uttering a word because she was a newbie.
It's tough for Sunny to survive by herself in the entertainment world, but the fact that she helped Hyomin get some air time was really nice of her.
