A photo of BoA and Taemin together is becoming a hot issue.

On Saturday BoA wrote on her Twitter, "'Music Core' Taemin. Taemin you worked hard today. Thank you" and revealed the photo above.

In the photo above, both SHINee's Taemin and BoA are seen wearing striped shirts giving off a couple look posing while sitting on a couch.

Their striped shirts and pants made them look somewhat like siblings and attracted much attention from viewers.

Fans commented on the photo saying, "The really look like siblings," "BoA really is a baby face beauty," and "They look so good together."

Meanwhile, Taemin performed with BoA for her latest performance of "Only One" on "Music Core."
