Answer: Authorial Intrusion. Or repetition.
Explanation: Repetition: The use of the word love is repeated in 3 lines within this poem. Another device would be metaphor because in this work love is being compared to being a game and being cruel.
Authorial Intrusion: Because the poem is written in first person, and the narrator is speaking directly to the reader.
Those are the two answers. Hope this helps :)
