So… When you were a baby on Earth, some aliens kidnapped you. You grown up as a prisoner on their ship with other humans and aliens. During this time, you make chilldhood friend with a female/man alien [give your description of your friend alien]. One day, other aliens rescue you from this prison and hire you as a guardian of the planets, to make sure there are no problems like attacks or anything else.

They gave to you a personal ship and you work as a partner with your alien childhood friend.

You're in the co-pilot's seat looking at other planets while eating chips until your partner joins you next to you
