JYJ Yoochun's hard work ethic and health has caused fans to worry.

On July 3rd, Yoochun wrote to his fans on Twitter, saying, "Although you have been completed in my heart... I don't know if it's because my vision is blurry... �but today's work was really difficult... I'm going to sleep now; good night~!! ^^"

Along with this comment, the tired JYJ member uploaded a picture of his dimly lit office, in which the bright screens of the monitors seem to outshine the early morning sun. As both the tweet and picture were posted around 6:53 AM (KST), it seems Yoochun had been working on a project until dawn.



As Yoochun had only recently�contracted conjunctivitis, or "pink eye", fans have expressed concern for Yoochun's current condition, commenting, "It's nice that you're working hard but your eye isn't in good condition.... It's concerning,"�and, "If his vision is blurry, doesn't that mean he hasn't fully recovered from pink eye yet?"

In other news, the '2012 JYJ Membership Week' exposition, which was launched on June 28th, has recently concluded after its 4-day run.
