Why did SHINee's Key and Minho bicker with one another on 'SHINee's Wonderful Day'?

On MBC Music's 'SHINee's Wonderful Day', the members of SHINee were whisked off to different countries to enjoy a special vacation in the middle of their album preparations.

Minho who is a fan of soccer chose London, England as his destination to see more of the Premier League for himself. Key who is interested in vintage fashion also chose the fashion capital of London. Having both chosen to visit the same country, the two are said to have hilariously complained about spending even vacation time with each other, after already having spent so much time together over the past years.

After arriving in London, Key followed after Minho, to which the stoic Minho told him, "Don't follow me," and Key jokingly expressed his hurt feelings , "I think Minho doesn't like me," continuing to bicker on throughout the trip like brothers.
