Jooyeon put on a fierce, tough girl look for After School's upcoming return with their 6th maxi single.

As one of the members with a cute image, Jooyeon surprised fans by tattooing up her entire upper arm with the image of a woman's head for the "First Love" music video. For those of you who might be shocked, don't be worried because the tattoo is only temporary as it was done with henna.

If you look closely, the tattoo contains Jooyeon's nickname 'JuPal'. Fans commented, "I thought she could only do innocent, but she can be sexy too," "I wonder what the music video will be like," and "Jooyeon's getting prettier with the comeback ahead!"

Check out Jooyeon, her arm tattoo, and the rest of After School in the "First Love" MV on June 13!
