Sun-mi is all about terrible decisions and probably did not have a "Oh, I don't recognize you, you must be a freshmen, everyone will frown at me for kissing babies" filter last year... SO. YES OKAY. Maybe some makeouts happened at a party and later people were like "you know that's a freshmen..." and Sun-mi was just like "...so? She is very cute?"

Sun-mi also baaaarely makes the senior cutoff age-wise, so whatever. She will still totally flirt with you, Ree.
