Love By Starlight (Markiplier x Reader)

This is my first time making a person x reader thing, and whenever you see (Y/N), it means your name. I hope you like it! (by the way, cover was made by Shuploc, not me...you should check out their art, it's the best). Anyway, here's a brief summary of the story:

You have been an astronaut for almost three years, and you are 27 years old, one of the youngest astronauts located at Houston, Texas, Nasa's base. You've been on countless missions before, Mainly to the moon, with your regular team, but this time, your engineer quits and a new guy that is very familiar to you steps in in right before you are launched to uncharted territory. Will the new guy be able to help if a problem arises, or will everything go wrong?
