Next to the picture of he and JB posing chummily together, Jackson wrote, "The best leader JB hyung whom I love. Don't be afraid and don't you worry. Things will get better with time. We'll always be by your side no matter what happens. We'll be watching over you. Get some rest and I love you very much, hyung."�

Though it's not certain, it seems like Jackson is trying to make feel JB better about his ongoing spinal disc pain. It's very sweet of Jackson to say those affectionate words to support his leader. Cheer up, JB, you're lucky to have the nicest dongsaeng in the world!
