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 Stefan is sick, faints, and we see a flashback of him and his mother Gallia who wasn't the best mother out there. Mikhail is a bit confused at Humans and their diseases, but tries to help. He'll give Stefan some soup so he can recover.
But is 50o5e something you can recover from? Stefan seems troubled.
