Red Velvet's Wendy has stunned fans and netizens with her abs.

On an online forum, netizens recently couldn't hide their shock toward Wendy's well-defined abs revealed on the first day of Red Velvet's concert in Seoul. The title of the original post was: "The reason why audiences were shocked after seeing Wendy at Red Velvet's concert yesterday."
