Yoona is really successful as an idol. She still has that untainted, bubbly image for 8 years, since her debut, and her popularity is still at its peak. ㅜㅋ Despite all this, she still worries for her fans ㅋㅋ For me, out of male idols, Lee Joon is the best and as for female idols, Yoona and Seohyun are the best
