The variety show "5LDK" aired by Fuji TV is well-know for its host TOKIO. The program will be celebrating its 1st anniversary in October, and on September 23rd, a full collection was aired with some unscreened scenes.
One of them is the encounter of Oguri Shun and Arashi's member Matsumoto Jun. They didn't become good friends at the time they met each other, and even then went to drink, none of them were talking. "Maybe we can't be good friends." thought Oguri.
However, later on, they costarred in the TV Drama "Hana yori Dango", which became an opportunity for them to know each other, and to develop a good friendship. Now when they go to drink, they have a tacit understanding that whenever one of them "seems drinking more than usual", the other one would stop drinking and give the drunk one a piggyback ride home.
It seems these two are sharing a mature friendship between men.
