Beast's Yoon Doo Joon is known to be close to Jung Hyung Don. Both first knew each other when they were on "Sunday Night-Danbi". They have become friends ever since. On the program from JTBC "Package Tour Around the World", Yoon Doo Joon replaced Jung Hyung Don's position as his mother was sick.

Both Yoon Doo Joon and Jung Hyung Don are able to talk comfortably as they have been close. According to report from KoreanBae, he once called Jung Hyung Don to make him song for Beast. It was out of nowhere but he just wanted to give new strength to the group.

On the program JTBS's "Package Around the World", it was supposed to be Hyung Don to appear. But his mother was seriously ill and he needed to take care of her. It was just three days before filming, but as Doo Joon heard it, he then came as a special guest without any doubt, according to report from Soompi.

It was so nice of Doo Joon to give support for his friend that way. The episode was aired on Jan. 24 and it was a great episode. Doo Joon showed no hesitation to adapt with new environment in Switzerland. He could eat any food served for him.

The show is about men in their 40s who have no time for themselves and thus going on a vacation with package tour. The show is so fresh as viewers can see how they are doing in their vacation. Doo Joon was doing so well in the program as the replacement for his friend.

The landscape shown in the program is no joke. There are beautiful sceneries that the viewers can see. On this episode, Doo Joon was also able to reunite with Kim Yong Man from Sunday Night-Danbi.

Fortunately, Hyung Don's mother was fine then and he could be relieved. Don was lucky to have friend like Doo Joon who is always there for him.
