You and Hunk's team were close, good friends but then out of the blue, they disappeared overnight. so, you decided to investigate and eventually ended up being taken into space by some Galra.

Luckily Voltron was there to rescue you but you didn't expect it was your friends along with a few other people. they took you to the ship and explained the situation to you.

"That's basically it." Hunk says in a slightly worried tone.
