Like the good friend she is, Goo Hye Sun was recently spotted at a baseball stadium, cheering on her good friend Kim Joon at a baseball game for Invincible Baseball. Goo Hye Sun and Kim Joon go way back to Boys Over Flowers. Kim Joon always looked like he wasn't as close as the other cast members but I guess that was a wrong assumption. Kim Joon shared this picture on his Twitter. He wrote, "Thankful thing, perform some magic." The magic part of the caption is referring to Goo Hye Sun's self-directed movie Magic which open in cinemas from June 24th. They are cute!
