On March 8th, Starship Entertainment revealed that IU will be playing the leading lady for K-Will's comeback MV, "My Heart Is Beating". Still-cuts of her appearance were recently unveiled, which showed the young singer cozily drinking a large cappuccino for a scene that's reminiscent of "Secret Garden"'s 'foam kiss'. Considering how MBLAQ's Lee Joon was revealed to be the male lead yesterday, fans have been wondering whether Lee Joon will be the one to complete the 'foam kiss.'

K-Will's first title track, "My Heart Is Beating", will be released on March 10th. Source: Sports Chosun via Nate
