Girl group miss A member Suzy revealed her knowledge of old K-pop songs.

Yesterday she posted on her twitter, "I don't know. How am I Supposed to know~" along with a picture.

In the picture, she is wearing a pair of big headphones and is smiling brightly at the camera. Her pose is similar to the dance by Um Jung Hwa in the 90s. The message on her twitter was also part of the lyrics of this song.

Internet users commented, "She knows 90s songs too? Nice" and "She is so pretty." 

On the other hand, Suzy will begin her role in a new MBC drama this April.
