NO IT'S NOT AMONG US

It's Miro, my character.
He's an alien who borrowed a spacesuit from his astronaut friends.

The essence of the story is that Miro lives on a small asteroid (or not quite, I didn’t understand the terms yet), collecting space debris from different planets (in this world, there is life on other planets, but intelligent are only outside the solar system). Miro's favorite is Earth, one day he accidentally approaches it and meets with a team of astronauts, with whom he quickly becomes friends. But later, the alien learns that the mission of this team is to destroy the Miro's home, because it poses a threat to Earth. Miro cannot "unfold" the asteroid and save it, and cannot fly to Earth, because it will most likely be autopsied for study. He escapes from the space ship into outer space, feeling betrayed by the Earth.
