K.Will visited EXO's Chanyeol on the set of his own "You Don't Know Love" MV to show his gratitude for the cameo!

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.
