In Japan and China, yes. In Korea she is second most popular after Taeyeon and is very well known for being the face and being in actress. She is also one of the famous ones in America.
She's always the center of SNSD. Even Taeyeon says she's the image of the group. So probably. But since Taengoo is the leader I think she's after our Kid leader ♥ However, I love her!! To me she's the most famous :D
