Sungmin's wifey, talented musical actress Kim Sa Eun, appeared on KBS 2TV's 'Hello' on March 9 where she talked about her hubby's pending enlistment this month for his mandatory military service.

She revealed, "It's been 79 days since our marriage," and Lee Young Ja brought up his enlistment on March 31.  Kim Sa Eun said, "It's okay because I already knew all that, but I wonder what I would do all by myself."

Byun Jung Soo revealed that she had, prior to this moment, given Kim Sa Eun advice, such as go on vacation by herself or even take her in-laws with her so that Sungmin would be touched by her thoughtfulness during his enlistment.  

Kim Sa Eun nodded along, which the other MCs noted and teased her for not seeming excited about this.  She laughed and assured them it was nothing like that.  You can watch at 1:20 above!

In addition, Lee Young Ja asked her, "Do you and Sungmin often do skinship?" to which Kim Sa Eun responded, "The two of us are already one body, so we're usually always stuck together."

Lee Young Ja continued, "Is he good at skinship?"  Shin Dong Yup replied with a suggestive remark that made everyone laugh, "What can't idols do?"
