Girls' Generation members Hyoyeon, Taeyeon, Tiffany, and Seohyun celebrated Sooyoung's birthday.

On February 10, the girls got together to throw a birthday party for their dear member and friend.

In the Instagram photos, the five girls are dressed in vintage clothing at cafe Kudeta, sporting thick-rimmed glasses against the backdrop with the phrase 'Happy Birthday Forever Young'. While birthday girl Sooyoung is about to blow out her candles in a rose-themed chocolate cake. It's great to see their close friendship!
