I mean, in my dreams, humans banished all the monsters underground. And I'm underground and didn't fall in. Also I'm a skeleton. I think that's probably a good giveaway.
It is. But they made friends anyway. I mean, I know that I shouldn't trust humans but like, this kid was good. They didn't even try and hurt people. Like Undyne actively tried to kill them several times and they still helped her and became her friend.
