All warfare is based on deception. You meet Yongguk time and time again; you two are military pilots, just on the different sides of the war. In all these lifetimes, you never once managed to save him. (Or, the story where you and Yongguk are stuck in some messed up timeloop.)

Yongguk is trying to be a good leader to make up for his past, but his crush keeps getting in the way. You are who you are, and he is who he is, and when someone is born with innate crap luck, tends to happen. It just happens. Still, you are the beat his heart never made and that almost-love story he never got to tell.

In which everybody knows that Youngjae has a crush on you. Everybody, including you.
