Countless people die young in this world, each in their own way. Yet some of them pass the tests set by interstellar commanders and are granted a chance to be reborn.
But nothing comes for free. Rebirth has a price: every Host must complete missions and earn an interstellar title to truly be born anew.
System Number Thirteen began its career with the earnest ambition of winning the title of "Best Interstellar System."
When the System eagerly bound itself to its Hosts, it said, "Come on, come on! Your mission is to end the chaos and unify the realm, earning the title of Emperor of the Turbulent Times. Your mission is to scavenge in the entertainment industry and become the Garbage King as soon as possible. Your mission is to transmigrate to Snake Island and earn the title of Strongest Snake Lunatic..."
The Hosts: "... Are you kidding us? One is a rich second-generation heir who does nothing all day, one is a celebrity whose every move is watched, and one is an unemployed person terrified of snakes..."
What kind of misery are these assigned missions? Is there still time to die and get reincarnated?
The System: "What did you say? The wind is too loud, I can't hear you!"
The Hosts: "..."
So the Hosts all spoke up: "There's no way we're doing missions! Not in this lifetime!! Don't even think about it!!"
The System: "Ding! Please be civil, Hosts. The person you fell in love with at first sight is about to face danger. If you keep slacking off, someone else will steal them away, then torment them physically and emotionally until they meet a tragic end."
The Hosts: "!!! There's no way we're slacking off! Not in this lifetime!! It's just a cheesy mission, we can do it!!!"
In short, this is the story of a bunch of people who used to slack off, working tirelessly for their sweethearts until they reach the peak of life.
