The character is a bit disturbed by finding out that his lady is something else. Something a bit unhinged. I'm imagining something with a Wild Cherry guitar and bass.

Tyrannical women, you'll be the death of me
Beneath that sweet facade, you hide a wicked soul...

A hard rock song with a driving bassline and distorted guitar, reminiscent of Wild Cherry, punctuated by explosive drum fills, creating a frenzied, unhinged atmosphere, the melody is intense.
