Kim Woobin sent his support to his dear friend Do Kyungsoo in the sweetest way possible, quite literally.

On August 2, Coffee Pong, a coffee truck firm, disclosed on Instagram that Kim Woo Bin had given a considerate present to D.O.'s film set. The coffee truck's banner reads, "I am pulling for the actors and crew of 'The Moon.'" Please look after my Kyung Soo (D.O.'s true name)." The banner adjacent to the coffee truck bears a kind message for D.O. that reads, "Don't get wounded, Do Kyung Soo." Do Kyung Soo, don't become sick. Do Kyung Soo, eat well. Do Kyung Soo, get some shut-eye. Do Kyung Soo, scream!”

D.O and Kim Woobin met through mutual friend Jo Insung and have maintained a blooming camaraderie through the years.

The Moon relates the story of a guy who is left alone in space and another man on Earth who is anxious to help him. Sol Kyung Gu will play the man on Earth who will embark on a rescue expedition to find the missing one, while D.O. will play the man who became separated in space due to an unanticipated catastrophe.
