Girls' Generation's members Taeyeon and Yoona showed support for member Seohyun in the musical "The Moon That Embraces The Sun".

Yesterday, Taeyeon posted on her Instagram, "Seohyun's voice is so nice... I think I'm going to get sentimental every time I see Seohyun now. So proud of you, our little one! Thank you for showing us a great performance" along with a picture.

In the picture, Taeyeon, Seohyun, and Yoona are standing next to each other, posing for the camera. Seohyun was still in her musical outfit.

Internet users who saw this commented, "I liked her voice too," "They all have such great vocies," and "All three are so pretty."
