[For example, in Aurora's vow, she promises to give you her heart and body.]
[That means if someday she starts losing her feelings for you, she still needs to find a way to love you again because the moment she fails to do that, her soul will be obliterated.]
When Gon understood this, he realized that Aurora was serious.
The vow went both ways: she gave her heart, but Gon needed to do his best to make her happy.
He then started to ponder about it, what to do, and how things would develop from this point.
He then asked the system if Aurora could be brought back to his world.
[Aurora is contracted, so you don't have to pay for her to go to your world]
[I don't know who she's contracted with, but we have different ways to travel between worlds.]
[So, the moment you do that, her ability to travel to other worlds will become active, and she will then be able to travel by herself.]
