He is also a huge fan of yours!— اکانت دوم بارونتون (@love_means_exo) April 16, 2021Welcome to Korea @coldplay! Once your quarantine period is over, we hope you can take some time to watch @thebox_movie. A Sky Full of Stars was used in the film & the scene where it was used was one of the film's highlights.
