Damn dude, they stripped a lot from the wn, huh
I understand that they need to keep up the pace, but the way they did it made the situations have a lot less weight
Unfortunately the manga doesn't go into enough details
In the novel, the goddess promises the sister to "reincarnate into the same world as her brother", and the way she said to hide probably means that she already placed where they're gonna reincarnate.
That's why she said that he should run...
Yeah, he should just go with her
Even if he doesn't don't love her now, he can learn to love her if he works on it
Go all the way, before it's too late
He should just say "fuck it" and do it already
If he did go all the way before in the situations, he wouldn't have found out that everything is a lot shittier than it is, so I think that it's better to escape now that to go deeper down the rabbit hole
