“It’s fierce kiss will stay on your lips, possessive and faithful as we are, for as long as we are”
Idea and tone beginning to change
Lingering pungent scent of the onion is compared to a kiss
Romantic and soft image compared to violent, possessive image - contrasting idea
Enjambment emphasises ‘possessive’ - a kiss can be gentle but it can also be a sign of possession
Suggest that trust/loyalty may be temporary - there is an unhealthy bond between the narrator and the person they’re speaking to
