Fans are worried about Sunmi after seeing large bruises on her knee.

On March 8th, Sunmi posted various photos on her Instagram with the caption, "BALMAIN 2021 F/W SHOW Welcome aboard✈." 

In the photos, Sunmi shows off her charming vibes posing wearing a short one-piece dress from the brand, but netizens took particular notice of the dark spot on Sunmi's left knee.

It seems that Sunmi's knees were bruised from the choreography from her new song "Tail," which requires Sunmi to be on her knees. After seeing Sunmi's photos, netizens commented, "She must've practiced so much," "That looks painful," and "All I see are her knees."

Previously, Sunmi complained about having knee pains, so her fans have become more worried about the artist. Meanwhile, Sunmi released her new song "Tail" on the 23rd of last month.
