Okay, I'll explain more~

Hello, Gwen.
 
Well.. None of what you mentioned is similar to this program. It's so difficult to explain. So to say it has no specific form. The 5 men come up with new ideas every week, and do what they planed.  While doing missions and activities, they also make fun statements and do some slapstick comedies.  The picture below is of the five men. Guess who is who!
 

 
And this is the link to website of the show, but it's all Korean so maybe you cannot reat it.

You also mentioned the show, "We are married". Yeah, it's also very interesting but I don't watch it these days. That's because I watch other show in the same time, "The Family". It has 2 females and 6 males and they visit house in countrysides where old married couple lives. There, they do what the olds ordered while the olds are out of town. They also make fun statements and do slapstick comedies. It's a newly made show, but it is really interesing.

 
There are more show that I'd like you to know, but let me tell you them tomorrow. ^^
 
For now, let me say about today. It rained cats and dogs all day long, since it's the summer rainy season in Korea. I view it as of both good and bad effects. It makes the air temperature low, but it also damages roads and fields. So I wish the rain will stop soon.
 
Tomorrow, I go to an English academy. I will study hard so that I can get good English command, haha.
 
Then, let me stop writing for now.
Catch you tomorrow~!
