One thing I noticed is SHS use of Korean vocabulary that is highly wide range, highly pointed and wordy classic words, for example, in the radio show with KMS and Ugly Duckling variety show. Very uncommon, not that I think people in Korean entertainment industries are less educated. She is also known to have good memorization for her lines in her past interview. She always corrects KMS's lines. That means she memorizes the other actor's dialogue too. This probably comes from constant coaching from parents, education or high IQ. It makes me curious about her family and her up bringing.
Not sure if she will be compatible with just any guy in a long term relationship. She is cute and bubbly, but can be intimidating when you listen to her and in your mind go "huh"?
