On the April 9 airing of KBS2's 'Hello Counselor', Tzuyu shared that she made a mistake in her early debut days because of her poor Korean speaking skills. Tzuyu explained, "When sharing my final comments, I said, 'Today was so boring' (?? ????? Oh neul ji gyeo wusuh yo) and everyone suddenly burst into laughter."
She was actually intending to say, "I had much fun today." (?? ????? Oh neul jeul guh wusuh yo).
