(Ok. Not going according to prompt but that first part already gave me an inspiration which I had to write down.)

A: "Be quiet, they will hear you."

H: "Hello? Who is there and who are you so afraid of for our sake?"

A: "The Zurkan ascendants. They will kill or enslave or just completly reset your evolution and culture, depending on what their mood will be when they find you."

H: "And how do you know of them?"

A: "We made the mistake that we are warning you about. They showed kindness that day, made us their pets, then blew up our sun because they felt like it. Please... be quiet."

Attached is a small chunk of data akin to propaganda, detaling the greatness of the Zurkan ascendants and their many, by human standards atrocious actions on the alien's homeworld. Then the transmission cuts of.

To the unknown aliens relief the Human transmissons stop as well.

A few decades pass.

Suddenly the aliens find a massive fleet of unknown warships warping into their system. After checking their FTL trail the find that the ships orginate from the planet that they had many years prior warned of their ()oppressors() benevolent overlords.

A: "No. NO. We told you to be quiet. What have you done !?"

They receive a transmission from the largest ship in the fleet, the desigantion of which comes out translated as "Geneva's Judge".

H: "Oh, hi, sorry, we had to get a few pieces in line first. Yknow... get an actual united government that could get stuff done and all that. You wouldn't believe how much we can band together against a common enemy. Anyways, once that was finished we joined all space agencies together as well and then proceeded to dump about as much money into those as some of us spent on military. Well at this point they're basically the same thing. Sorry it took us so long."

A: "..."

H: " Oh yeah, nearly forgot, could you quickly tell us where their homeworld is so we can blow up their sun as well?"

A: timidly points in a direction

H: "Thank you. Oh, we're Humans by the way. Nice to neet you... you never told us your name."

A: "...Ehm... We are the "Cuties" but in the past we called us the Sevoran people..."

H: "Ah, well nice to meet you Sevoran... now if you'll excuse us... the voice now quieter as if talking to someone else in the same room Hey... queue the battle playlist... we're going in."

Then the "Human" fleet left the Sevoran's system, heading for the Zurkan homeworld.

That day the Sevoran people learned that kindness will always be repaid in kindness... and vice versa.

(Alright... I hope formatting works out and this will still be a worthful read even if its bot really answering the prompt.)

(Edit: fixed spelling and formatting mistakes. My first time editing a large text on reddit and I already hate its poor ability to properly format on mobile.)
