Girl group Wonder Girls' member Yeeun revealed Sunmi's birthday dinner.

Yesterday, Yeeun posted on her Twitter, "Sunmi's birthday dinner. It's a day late but happy birthday" along with a picture.

In the picture, Wonder Girls' member Yeeun had made a birthday meal for Sunmi herself. There was a variety of food from salad to pizza.

Internet users who saw this commented, "Your friendship is so good to see," "Happy birthday, Sunmi," "Yeeun's birthday is coming up too," and "You must be good at cooking."

Sunmi left Wonder Girls in January of 2010. The friendship that seemed to continue even after Sunmi left caught much attention.
