SEE ALSO: Chanyeol cries for losing Lee Ho Jung in K.Will's 'You Don't Know Love' MV

Starship Entertainment tweeted, "What were they like on the set of K.Will's 'You Don't Know Love' MV? Even though it was raining, EXO's Chanyeol performed enthusiastically for the music video and K.Will came out to support him! It is really a warm�atmosphere�^^."

In the BTS photo, K.Will protects the precious idol member from the drizzling rain by holding up an umbrella. Their bromance looks just as sweet as the romance in the music video, and they give their thumbs up to show that filming is going smoothly.
