Cover art for Wet Road lyrics by Scout Niblett

The lyrics are great, and more complex than you give her credit for. It's basically a song about a doomed relationship.

She has already captured him and just wants to be with him. For her, that could be paradise.

The "wet roads" on the way to his house signify the problem, because he's the one who doesn't know how to "play with what [he's] given".

That explains the somber end to the song: this relationship is "only for a little while." While she wants to share a space with him, she also realizes that the "wet roads" will make it difficult if not impossible to sustain this relationship.

Just a theory.
