Ga In met up with Star N for an interview and brought up the fact that Girls' Generation's Sunny performed her song "Bloom" for a concert stage.

She said, "I saw that performance, too, and [Sunny] had a lot of concerns about it.  I met Sunny first at the year-end awards ceremony and said, 'I heard you're performing,' and she asked me, 'Unnie, what do I do?  How do I do it well?'  So I told her, 'You look sexy even when you just put on the outfit.'"

Ga In continued, "I told Sunny, 'You look sexy even when you're wearing just jeans and a T-shirt,' and she said, 'Ah, unnie!' and seemed to like it.  Sunny has her own sexy appeal."

She said, "In my case, I was not a singer who exuded a sexy atmosphere like that from the get-go.  I am the type that studies a lot to see what I can do differently from those who have a lot of that talent from the very beginning."
