Actress Shin Se Kyung did not attend her boyfriend's two-day concert, held on January 1st and 2nd. Much attention has been put on her attendance, since it was revealed late last year that she was seeing SHINee's Jonghyun. SM Entertainment eventually responded, "We've been informed that Shin Se Kyung will not be attending SHINee's concert today (Jan.2).  She is filming for her movie, 'Blue Salt', with Song Kang Ho." Meanwhile, SHINhee managed to gather over 20,000 fans for their first concert since their debut two years and seven months ago. Jonghyun, who has a leg injury, had Chinese trainee Issing take his place during a portion of his performances.  Jonghyun greeted, "I'm glad to be able to spend the New Year with my fans.  It's a great start this year."
