She replied, "I didn't do it intentionally.  I hear often that my voice matches the springtime well.  I hear that it's a voice that can get hot in the summer."  She also talked about her practicing method with, "I do not get lessons.  I sing a lot of Disney songs which have a tone that's similar to mine," and performed songs from movies like 'Tangled,' 'Frozen,' and, 'The Little Mermaid.'

Baek Ah Yeon also revealed, "I'm scared to sing.  I'm the type that looks at every single comment, and whenever I see a malicious comment, I always feel hurt.  I can't leave a malicious comment, but I press the down button diligently."
