Preparations

Even until now, Cain didn't put in serious thoughts on how he should break the news to Amber. Admittedly, he was a bit afraid of how she would take it. 

He could say that he has a firm grasp on Amber's personality, but he isn't all-knowing. Amber could react in ways beyond his scope towards his God Galaxy origins. 

And this wasn't even considering his desire to bring her along with him. 

Compared to themselves, Cain believed this was a genuinely complicated matter.

Still, Cain didn't want to simply leave Amber behind. Doing so left a sickening taste in his mouth as if he would make a decision he would regret for the rest of his life. He felt it would be a mistake he would never be able to make up for, even with his massively long lifespan.

More than anything, Cain didn't want to make any regrets in his life. He would be wasting his gift at his new life while also trampling over his desires. So his only option now is to consult his grandmother.
