Interstellar Diplomat, Stop Getting in the Way of My Infrastructure Projects

What's so bad about the apocalypse? Even in the apocalypse, there are technical soldiers with ideals, helping humanity survive and build a better home for generations to come. Though Song Yi is just an ordinary technical soldier who can't fight on the front lines or make waves in politics, he is also a first-rate (unknown) young man of the apocalypse, who is quite high-profile (utterly low-key) and comes from a spotless (extremely complicated) background (are you sure about that?). Song Yi: “Commander, I'm just a technical soldier. I don't need all these care packages.” Fell Loin: “No, you do. Building a new world is hard work, and these will lift your spirits.” Song Yi glanced at the care packages and rolled his eyes. How are they supposed to lift my spirits? Why don't you try lifting mine? Fell Loin × Song Yi (1v1, happy ending. He chases his wife all over the world, only to be accused of harassment.)
