The child actor Park Ji Bin and singer IU revealed a sibling-like picture.

Today, Park Ji Bin posted on his Twitter, "At IU's concert on Sunday, with IU who sings well and dances well and talks well, I covered my face because I looked bad..." along with a picture.

In the picture, IU and Park Ji Bin are standing next to each other, both making V's at the camera. IU is showing her smiley eyes with her clear skin.

Internet users who saw this commented, "IU is getting prettier," "Is Park Ji Bin copying Bridal Mask right now?," "I want to see his face under that sticker," and "I didn't know they were close."
