Dust Safe Guard

In a world where the air is polluted and it is impossible to breathe without a gas mask, 'Dust Safe Guard' Dong Wan succeeds in evolution after hard work, but loses the most important thing. It is the era of the new normal that cannot be easily predicted, but the really important things will not change. It may seem like he's doing a trivial job compared to his abilities, but he cheers for Dong Wan, who is doing anything in search of the meaning of life.
