On June 4th, JYJ's Yoochun celebrated his 25th birthday with a surprise party thrown by his fellow JYJ members. Representatives revealed, "Yoochun turned 25 on the 4th, but he was performing at JYJ's San Jose concert for their world tour that day. Junsu and Jaejoong held a surprise birthday party for Yoochun during the middle of the concert, which continued afterwards at their wrap-up party." Junsu also tweeted, "I genuinely congratulate your birthday, Yoochun", while Jaejoong wrote, "I love you." Their representative continued, "Yoochun has a busy schedule but he's monitoring his drama, 'Miss Ripley', through the internet. He's glad because the viewers have been leaving positive responses. His character in the drama is both respectful and smooth, which matches well to his real life personality. He knew that it fit him well, so he really wanted the role from the start."
