Mikhail is an Angel who is lowkey bad at being one. Heaven's expectations are just a bit too strict for him, which is why he's applied to fight Demons on Earth. Sadly for him, even if he did do his fighting Demon job, Heaven did not provide him with a wage or housing so he's stuck with his neat freak of a roommate Stefan, who would certainly make a better Angel than Mikhail does.
Through shenanigans and bad puns, these two will get together... so long as Mikhail can avoid ending up on the Demons' wing black market.
In which Mikhail and Stefan attend that damned pizza party. But... things go south pretty quickly, first, Ruby the HR succubus shows up, then Stefan punches his co-worker who was also there...
Mikhail and Stefan have no choice but to leave the party, but this leads to some bonding time (with additional puns)
