JYJ's Yoochun tweeted on May 30,�"Taesung hyung, Minsoo hyung. We had a lot of fun. Passed out Yoochun, mental collapse Yoochun. Did we always have this kind of relationship?"

In the photo, Yoochun is sleeping soundly, unaware that he is being photographed. His fellow 'Rooftop Prince' co-stars Lee Tae Sung and Choi Min Soo made hilarious facial expressions for the camera as they sat beside Yoochun in bed.

Fans responded, "Yoochun is so cute fast asleep like that," "How can he sleep so soundly," and "He must be so tired."
