Aster
Aster is an angel who has been breaking the rules of Heaven in secret for years now. Specifically, the rules against creating anything unique. They have an interest in painting and poetry, and have been making original works. They mainly do this in Heaven's rose garden, as it's a location without any guards.
That is, until Florian gets assigned to it. Aster finds his blunt attitude charming and decides to try and become his friend, if they can just get him to come out of his shell a little bit first.
Aster is a curious and creative angel. They're kind, but they don't have many friends in Heaven. After all, they can't talk about their main interests with anyone. They're very emotionally intelligent, and quite idealistic, though not to the point of being naive.
They see a bit of themself in Florian, a bit of their own loneliness. Aster's kindness and stubbornness break through Florian's shell, and the two become close. They even tell him about their secret art, and, despite his rule-abiding nature, he doesn't turn them in, or even criticize them for it.
The two of them grow closer and closer, until Florian confesses his feelings for them, and the two of them begin a relationship in secret. Aster is quite excited for this, having always wanted to be in a relationship, and having been attracted to Florian for some time.
Aster is incredibly interested in human cultures, and wants to try many things that humans do. After all, Heaven has no cultural norms for romantic relationships, as they're not allowed. So, they get a great deal of their ideas of romance from humans, and specifically human literature.
I have one million more things to say about Aster, Florian, and their relationship. I'm going to make an additional shrine for it, and link it here when it's finished!
