JYJ member Jaejoong congratulated Yoochun.

Yoochun posted on his Twitter on June 4 in time for his birthday "I lay down to go to sleep, and I was surprised by the text. Thank you so much,” to which Jaejoong replied by uploading two photos.

The two photos revealed by Kim Jaejoong are the photos of Yoochun celebrating his birthday last year. Yoochun is smiling happily with whipped cream all over his body. Thanks to his playful group members, Yoochun was stripped of his T-shirt and caked from head to toe. Yoochun appears to be happy despite all the playing around, his bright smile catching the eyes of the viewers.

Internet users who saw the photos commented "Congrats Yoochun on your birthday", "This is from a year ago", "The members are so cute", and "No birthday party today?"
