What does betrayed with a kiss mean?

Could you please elaborate on the phrase "betrayed with a kiss"? It seems to carry a dual meaning, where the act of kissing, often associated with affection and intimacy, is somehow juxtaposed with the concept of betrayal. Is it referring to a situation where someone expresses love through a kiss but actually has ulterior motives or intentions? Or could it signify a moment of deception, where a kiss serves as a disguise for a deeper form of betrayal? I'm curious to know how you interpret this phrase and the emotions it might evoke.
