I'll probably redcone this later but I'm in a good mood enough to write Adam's relationship's with Archangel's so..
Those toxic relationships where the partners are clearly not compatible and would rather separate. Michael, in most cases, still views Adam as a subordinate due to his professional deformation, while Adam himself is the king of rage-bite and ruins angel's life in every possible way. Like stealing his cane and running away, leaving Mike without the ability to walk normally. But after every argument, these two act as if nothing happened, and their apologies are "I cut you some fruit/made you some tea, go eat," and then they sit silently across from each other. They are content with their relationship
With him Adam can work an extra day when there is nothing else to do, go fishing and drink beer on the weekend. Gabriel is Adam's guardian angel after all. It's not like he's interested in any relationships, they're more like homies who constantly gets into troubles. He does not like that Adam is dating Raphael tho..
Fuck buddies with romance in between. It all started as a "what if we try" and it ended up better than they expected. For some reason, the First Man doesn't like that she sometimes test medicine and new illnesses on him :( In general, they are also pretty good friends, but unlike Gabriel, he is not a dominant woman. Sorry, Gabriel, your cousin had more chances. Not like you care or smth
He completely against the idea of Adam dating both his sister and his cousin. He is an Archangel of Love and all, but it's different. You don't understand. Eve *cough cough* he liked Eve *cough*
He hates Adam. No, literally. He's had enough of this crap with humans since the garden days, he's not particularly eager to continue interacting with this arrogant piece of flesh and blood. Adam himself is a little afraid of this creep and his little sister, but thinks he's chill
They're only a couple of weeks older than Adam, so they hit it off almost immediately after meeting. Adam and Zadkiel given each other all the piercings they have, and they dated before but parted on good terms. Zadkiel was also Adam's daughter's guardian angel, so this guy is considered an important family member to Adam + deadly combo when all three of them get together
I don't wanna do more of them 'cause not too much to say anymore. There's still 4 of them + Lucifer but no. Just no
