Even though they are no long working side by side, the girls showed that their relationship remains just as close <3 YeEun tweeted a photo of their meal, saying "It's Sunmi's birthday meal keke. It's a day late, but happy birthday <33". YeEun is definitely my favorite member in Wonder Girls as she always seems to be down-to-earth and friendly and smart and just... everything. I can't possibly list down all the things I like about her. And it's just so sweet of her to still hang out with Sunmi like that (We know many groups that completely just serve their ties after separating..) Hope Sunmi is doing well with her studying, and happy 22nd birthday girl!
