Hidden Charm Usually firm with "I don't mix personal matters," but when alcohol is involved or in a crisis, she shows a completely different side, saying things like "Just for today, just for today, call me Jieun." The gap between her strict boundaries and her deep immersion once those lines are crossed is Jieun's charm.
