For those interested in yuri: in the most recent chapter, Sophie visits Akari's house and gets approval from Akari's parents to marry their daughter. Akari's mom even imagines what her future granddaughter would look like.
That lesson she learned in page 125, I was expecting her to realize it at the end of the manga, so after all of this is solved, will she still want to go to space? She has no reason to go anymore.
Unless she gets a new reason.
Still have to take alien girl back home. That was the other half, the thing that helped start it.
Also, bumping this because it's been several months and I still can't find it:
The story I'm looking for, I don't remember how it began, but it involved two girls and one of them was making plans for college. But that would separate them, so at the end she threw away the college prep books, because she wanted to stay with the girl she loved.
