It was just another day for Sarah, the 30 year old woman has repeated the same mundane and boring routine after finishing college and getting a job in human resources of a small company, wake up, go to work, return home tired, sleep and repeat, so after another tedious and tiring day at work she gets back to her apartment, she lefts her purse in the sofa and sits, it was like any other day...except for the spaceship parked in the living room....WHAT!?, it opens a door and a weird and green alien woman gets out of it, Sarah screams and falls to the floor shaking in fear, the alien looks and walks towards her, Sarah grabs a broom trying to apart her from her but the alien gets to her and puts her hand with 4 fingers on her head, after that she falls unconsious, later she wakes up and feels weird, she cant say what it is exactly but everything feels different, she looks down and sees a green and weird body with tentacles, she screams and looks up only to see her body moving by her own, she screams, she swapped bodies with the alien, the aline inside her body simply smiles and helps her get up presenting herself as "Sol-Arya"

Sol-Arya: Congratulations, human! You are the fortunate participant in the Zhalarax planet program. Our planet will explode in 5000 years, so to prepare, we scout for possible planets to colonize, making all the population swap bodies with ours. I was assigned to this planet. I will use your body to collect information. Everything is here in the memo. She makes a weird pose with her arms and gives Sarah a weird cube that has holograms in it in a weird language.

Sarah: ...GIVE ME MY BODY BACK!! She screams scared; her new alien body feels weird; she has 4 fingers and insect features; she sees weird colors with her new eyes, and she has a lot of tentacles on that seem to move on their own.

Sol-Arya: "Oh, do not fear; I will give your body back once I get enough information about everything on this planet," she smiles, doing the same pose that seems to be a weird kind of formal greeting on her planet. The idea of a whole planet of aliens swapping bodies with all of humanity sounds really terrifying to Sarah, but since the alien said it will occur in 5000 years, she calms down a bit. She doubts humanity will manage to get that far to live another 5000, so having no other option, she decides to help, wanting to swap back as soon as possible.

Sarah: Uh...sure...you can ask...

Sol-Arya: Oh, how exciting! I have so many questions! For example, I saw humans have different skin colors. Does that give them different abilities? For example, in Zhalarax, the blue-skinned Zhalaraxians breathe underwater, the red ones spit fire, etc. Is it the same with humans? Oh, and I see our bodies share some features. She squishes her new big chest. I assume these two also store acid, right? She then blushes. Oh...it seems it's a sensitive part....

Sarah just blinks and wants to cry. Why her? Why is she the one dragged into this mess?
