[talk] Even when I hear the whistle now, it still sounds completely unsophisticated.

Today I suddenly wanted to hear Blackpink's whistle

So I listened to it, and even now, it doesn't sound old-fashioned at all, but rather sophisticated.

Do you hear whistling often?

I really like it when I listen to it sometimes

I think it's a sophisticated and very attractive song.

This is a song that only Blackpink can do.
