Defconn revealed Kim Jong Min never contacted him after '1N2D'.
On the November 21st episode of 'Hangout With Yoo', the two former castmates appeared as guests, but neither seemed too excited to see each other. Yoo Jae Suk then questioned, "Why are you greeting each other like strangers? Didn't you both appear on '1N2D'?"
Defconn responded, "Kim Jong Min doesn't contact me after the new season of '1N2D' started," expressing disappointment, and Kim Jong Min admitted he didn't. Defconn then said, "You only contact me when you need me for a broadcast, don't you," and Kim Jong Min replied, "I contacted you when I had my own broadcast."

So I guess they just have a co-worker relationship and only see each other at work-related events. Nothing wrong with that. I'm not buddy-buddy with all my co-workers or former co-workers off hours either. It's likely that Def-conn doesn't contact him either. Friendships are a two-way street.
