Do You Have A Mate ?

The accident happened as they were leaving Adrian; Rocky is still unconscious, and Grace is doing everything he can to clear his head while waiting for his friend to wake up. As for the young Mandragorian, he hasn't fully recovered from the injury he sustained in the accident. The two of them are trying to learn a little more about each other while Rocky sleeps, still right beside them...

I discovered the world of Project Hail Mary, and I have to say I'm completely hooked... I haven't had a chance to read the book yet, but don't worry-I'll be getting to it soon! And since I have a story of my own in the works, I came up with a crossover between my universe and that of Hail Mary.
I tried to stay as true to the original story as possible, and I apologize if there are any mistakes...
P.S.: English isn't my first language, so I apologize for any typos.
To give you a simple background, my character, named Samaël, comes from a planet that looks similar to Earth but is called Mandragor. Samaël is a young elite soldier highly skilled in combat. He is a serious young man who often puts others before himself. And to fit into the PHM universe, I imagined that Mandragor's star was also dying, so a crew was sent to Tau Ceti to find a solution. But an accident occurred, and Samaël found himself all alone. It was on the way to Tau Ceti that Grace and Rocky stumbled upon him and saved him. The rest is the rest of the story, with another alien by Grace's side.
I want to make it clear that this is just my idea, and if you don't like it, then don't read it.
This is just a first draft, and if you like it, maybe I'll write more.
