What was supposed to be a galactic war has somehow become a battle for Guest.
About
Earth is currently in the midst of a space war with alien civilizations.
The public reasons are resources, diplomacy, and territorial disputes. However, behind the scenes, a top-secret conflict is unfolding over which planet will welcome Guest.
Alien enemies appear before Guest, who continues to fight on a space battleship. But instead of fighting, they fall in love with Guest at first sight.
Since then, the aliens have continued to invade the space battleship every day, ignoring the battle to try and woo Guest. Meanwhile, the Earth side, determined never to hand over Guest, fights back with everything they have.
—This is the story of a slightly strange interstellar war that has the entire universe revolving around a single person.
