"The most romantic thing I can imagine is flying through the universe with you in a spaceship. The ship and you are my home."
Feng Sinuo thought he would die in the explosion, but when he opened his eyes, he found that he'd been rescued. The more he looked at the person who saved him, the more familiar they seemed.
Then he took a closer look and was horrified: Wasn't this the omega his mother had forced him to marry back then?!
The omega had a screwdriver in one hand and machine oil on the other, with a chubby baby in their arms. Looking down at him, they smiled and said, "So, the planet we're on is about to explode. Your mental strength is high enough to pilot a mech, right? Hurry up, stop wasting time. We're escaping together!"
Feng Sinuo: "W-wait!"
A goofy alpha soldier with powerful mental strength who loves being in a band x a sickly, beautiful, tragic omega mech engineer who's always covered in machine oil.
A significant size difference, but they're evenly matched mentally.
Interstellar + postwar + escape + stockpiling supplies + construction + mechs + ABO + military uniforms
That's right, it's an escape story: They travel romantically through the universe in their spaceship, upgrading it step by step and rebuilding after the disaster.
