H1-Key showed their cool and refreshing vibes in the MV teaser for "Run". 

In the teaser video, the members of H1-KEY visit a skate park, go for a drive, and play mini golf in the backyard like high schoolers on summer vacation. H1-KEY's new comeback title track "Run" is said to be a teen pop-rock genre with a dynamic performance. 

The girl group will be returning on July 6 at 6 PM KST with their 1st Maxi single 'Run'.
