Ok after some thinking I got a few I like,
Also my story is poly so I thought it would be fair for them to have a song between each ^^
Vernon / Azreth - Baby its cold outside (you choose which version you like the most)
Their love is quite 'old fashioned' Azreth is always trying to slowly break down Vernon's barriers and slowly over the story he succeeds... And this is exactly what this song is about so it fits them perfectly ^^
Vernon / Grey - Arctic Monkeys - Do I Wanna Know?
I like this one particularly because it fits BOTH of their attitudes towards one another, they are both shy guys, even if Vernon is a bit more knowledgeable of matters of the heart he is hesitant... so both of them slowly getting used to the idea of turning their platonic love into actual love is a fun thing to see, at least for me.
Azreth / Grey - Hot Blooded - Foreigner
The fun thing about this is that while both their relationships with Vernon are on a slow double boiler bath, their relationships to each other acts as sort of catalyst of sexual energy, they know what each other wants and are more than happy to deliver...And when they are not on top of one another, they are both thinking about it and teasing each other around. It's the encapsulation of those bromances you see in other stories, but RAW like two teenagers in heat.
Vernon / Azreth / Grey - Axwell Î Ingrosso - Something New
Funnily enough this is the least romance of all the songs above, but it fits their relationship trio really well, I wanted a song that made you pumped for being alive, a song that makes you just feel good without having to worry about much else, an upbeat and spirit lifting song.
Just like their meeting and relationship lifts all three of them, together they are no longer just disconnected pieces of sadness drifting thought nothing,
Together they are a force to be reckoned, but also an inspiring and generally fun loving.
