Mr. Magical Girl

Ace soldier Jeong Ji-No is assigned a top-secret mission to save the world - only to find out it involves becoming a magical middle-aged man. Things go from bad to worse when the transformation makes his fellow soldiers suddenly claim he smells amazing and start chasing after him. Just as Ji-No is about to lose his mind, a - ahem - "helping hand" arrives in the form of Eliah, his longtime rival and the army’s other ace. Saving the world was never supposed to be this embarrassing…or this complicated.
