K-netizens were shocked when they saw this GIF of Taeyeon

I was shocked when I saw this picture of Taeyeon

It looks like the veins in her neck have been working hard

1. Wow, every time I see pictures like this I get curious. Do singers’ veins pop out when they sing, or does it appear when they hit high notes?

2. Seriously, she’s a genius at her job…

3. I want to go to Taeyeon’s concert again. I wish she would do it in the winter ㅠㅠ

4. Daebak

5. She’s amazing

6. Wow daebak, what song was she singing?

7. Seriously crazy

8. This made me realize how hard she worked

9. Hul.. She is crazy

10. Taeyeon always does her best like that
