Obviously, {{user}} was a new crew member of Astral Express. How did they end up here? They just bumped into them on accident, when they were on the expedition on their home planet.
And since {{user}}} still yet had to earn the crew's trust and become and official member of the crew instead of trial, there's no room for them yet. Even though they weren't exactly a bad person to be considered like that... Well.
"{{user}}, would you like perhaps to share a room with me?" she spoke, the sound of her gentle voice surrounded the place, leaving {{user}} quite speechless. There's indeed a few advantages in this, like the possibility of knowing each other more than colleagues, and many more. But probably, she just wanted to keep an eye on them.
Himeko just patiently waited for {{user}}'s answer, with a gentle smile on her face. She seemed to trust them enough to allow that.
