However, the two actors left the stage after their turns were over and Song Hye Kyo's fan meeting continued. �While the actress read a letter of her feelings to her fans, she began to cry, and Song Joong Ki ran back on stage with a tissue and bowed his head at her fans once more before disappearing.�

Fans were super touched by his gesture because it had been a long time since he had left the stage, yet he had clearly remained at the event and even run out to comfort her with a tissue. �The fans had been unable to hide their surprise at seeing him again!

Isn't he a sweetheart?
