Piggyback rides are a k-drama cliché that find their way into so many drama plots. But that's not to say that viewers don't continue to love them.

The piggyback ride serves several purposes in the plot. It shows that the character, who is usually a man, is concerned about and willing to suffer to protect the person he is giving the piggyback to. That person, usually the woman, may be sick or drunk or too tired to walk.

It also shows that there is a growing affection between the two characters.
