lol maybe she should 'demand' something super luxurious as an offering. but assuming her powers 'worked', maybe she could've diffuse him with "So you want me to take her free will away and basically brainwash her into loving you?" because if praying to a god for your relationships to come true , other than romantic dreamer aspect, would come off as sleazy/underhanded to do if it's confirmed that gods are there.
(Tbh my first thought was how some ppl use the phrase 'pray the gay away' so other than 'pure wishes' at best it's selfish and at worse it's malicious but this is me overthinking a pointless one shot lol)
