Same members learning how to travel abroad and live there (as a holiday) independently.
Let me start by saying this, YOU WILL NOT GET BORED BY WATCHING THIS!!! :-)

They don’t read a script to do all this, it’s natural. They enjoy what they do in every episode, get some snacks and get comfortable and watch, there are scenes that will make you laugh so much that you’ll start crying and scene that are sappy (sad happy) it will give you tears of joy.
I highly recommend you guys to watch it. (There’s season 2, 3 and 4) :)
