That was really good; I liked the added humour at the end. The poem about her being a good girl when judging by the words she says at the end, she’s clearly not, or intends to be no more.
“I was a good girl,
too pristine and ethereal
to be interesting.”
““Damn,” I whispered. “Shit.
I’ll escape you yet.”
Those are to brilliant contradictions that explain there is more to a person than meets the eye. These lines:
“I rolled unexplored words
across an unpracticed tongue.”
Clearly make the person in who you are referring to interesting to the reader, it keeps us in suspense of what’s going to happen next as there’s a hint that revenge might happen, and from a good girl it is interesting to know what they are capable of on the quiet.
I like the structure of the poem; it works in favour of it though I haven’t entirely worked out why it’s written that way. But it definitely makes it read better.
