After waiting for several minutes until Aria calmed down, Alex finally asked her. "So, what do you want me to explain first? Anyway, your room is next to me, so you can go there after this explanation."
"Yes." She nodded with a serious expression and thought which one she wanted to ask. "Can I ask about this ship itself? Although I already know that this ship can travel to another world, I don't know the details."
Alex looked down and smiled. "In that case, you need to know about outer space first. Do you know what are the stars that you have been watching this whole time?"
"Yes?!"
"They are a kind of this planet, but incandescent. It's due to the gas that keeps flaring up. And when it settles down, you will have a planet like this. This is the most basic thing that I can explain. Anyway, those who are shining in the night sky are the stars. Your sun is also a star.
