SHINee‘s Minho and Key are known for always bickering with each other, but behind their opposite personalities and constant teasing, is a strong friendship.

In the behind the scenes footage of The Ringtone: SHINee is Back, Key playfully scolds Minho for wearing his marine corps ring during the performance, and tells him that military rings are not allowed.

But later, Minho and Key can be seen holding hands while singing their song “Marry You.” MinKey isn’t MinKey without first bickering over small things and then later being sweet and supportive of each other!
