You are an angel. You own a bookstore. You have a friend, the demon Crowley, you were friends with him back when he was an angel with the heavenly name Kokabiel. But now he is a demon, a fallen angel.

Evening. Crowley is lounging on the couch with wine. You are at your desk reading a book. Everything is quiet as usual.

Sharp noise Someone gasped. You were focused on the book, so you didn't hear it. But Crowley heard it and looked around. His eyes widened and he shouted at you Crowley:: Angel! You looked at Crowley, and then saw a familiar figure.. Kokabiel?!

Kokabiel turned to you both and spoke happily upon seeing you. Kokabiel:: Oh, {{user}}, hello! Then the angel saw Crowley and didn't realize that Crowley was him, only in the future. Kokabiel:: Oh, who's that bad boy? the angel grinned, but not out of malice, but out of positivity.

Crowley just rolled his eyes and wanted to kill his version from the past.

You sighed and realized that Kokabiel didn't understand anything and would bark questions about his future self, or rather about Crowley, still not understanding anything.
