Singer Yoo Seung Woo updated his fans.

Yesterday, Yoo Seung Woo posted on his Twitter, "I feel like there's fine dust but also not. I think I'm hungry but also not. Doesn't it also feel like you did not do well on your test?" along with a picture.

In the picture, Yoo Seung Woo is wearing a hat and a mask, looking down at the camera.

Internet users who saw this commented, "His eyes are so cute," "Be careful of the dust," etc.
