Eminem raps, "And right now there's a steel knife, in my windpipe". This is a metaphor that he uses to symbolize the emotion that are preventing him from communicating his vulnerable truth.
Later in his rap he continues, "Spewing venom in your words, when you spit 'em
You push, pull each other's hair, scratch, claw, bit 'em
Throw 'em down, pin 'em . . ."
This could be considered imagery as it leads the listener to imagine the heartbreaking scene.
In the chorus, Rihanna sings about him watching here "burn". This is yet another metaphor used to symbolize her feeling that he is allowing her to be in pain.
Towards the end of the song Eminem raps, "Baby it was me, maybe our relationship isn't as crazy as it seems
Maybe that's what happens When a tornado meets a volcano . . ."
It could be argued that this presents alliteration due to the repetition of the vowel sound "ay". This alliteration draws attention to the dramatic overall tone.
All throughout the song -- and twice at its end -- Rihanna sings, "I love the way you lie."
Because love is typically assigned a positive connotation, and lying a negative one, this demonstrates irony. In this she is conveying that she continues to love him even in toxicity.
Hope this helps
