Cover art for On Marriage lyrics by Carissa's Wierd

The only way I can make sense of this is as it were directed at two women, two stories in parallel.

One of a woman who cheated on him ["it's okay 'cause she's a slut], and he left her [when you're all alone], and he wants her to regret it.

And the woman he found [I feel home], married, and everything turned out okay in the end.
