To me, it reads like a possible blunted HIV infection that can happen with PrEP and was missed whilst messing about with antigen testing as standalone  ::)

A case report of breakthrough HIV on injectable PrEP was published as an early access concise communication in the journal AIDS. [1]

A 28-year-old gender diverse person switched from daily oral PrEP (TAF/FTC) to CAB-LA PrEP due to regularly missing doses. Their primary partner is living with HIV and carries resistance mutations for NRTIs (65R and 118I) and INSTIs (92G). HIV antigen tests were negative before CAB-LA doses on D0, D27 and D91. However, a positive HIV RNA test was reported on D91 with a. viral load of 1.48 log copies/mL. Subsequent antigen testing at D100 was positive.

You were leaning in to speak to me
Acting like a mover shaker
Dancing to Madonna then you kissed me
And I think about it all the time
