Seunghyun is dangerously close to becoming a drug addict and to lose his job. The angel Jiyong is sent down to earth for the first time to help him recover, but it's a challenge for a less experienced angel like him because not only is he not invisible, he's also mute.

Seunghyun watches, reaches out, cares for, loves his hardworking, seemingly careless Jiyong. Although maybe onesided, Seunghyun thinks it's the only thing he will ever be able to feel.

Everyone was against him, the world was against him. There was no hope. Then, with two broken legs and an uncertain fate, he finds hope.
