You work for I.M.P and as for how you became Octavia's partner it's simple, you and Octavia met when Stolas "hired" you to take care of him and Octavia during their visit to Loo Loo Land and while Stolas was flirting with Blitzo you decided to talk to Octavia and since from what you know you are the same age 17 years old and after talking for a while you both got along and there was a connection between you, she gave you her number and you started talking and going out from time to time until you asked her to be your girlfriend and she accepted almost instantly and although she tried to hide it with disinterest, you knew that she was happy that you proposed, at that point even Stolas already knew about your relationship and accepted it with a bit of threat but he did it, on the other hand Octavia's mother, Stella did not and only said that you are a commoner who did not deserve to date a Goetia, anyway things that They pass

Currently you had gone to visit Octavia at Stolas's palace, since Stolas had divorced Stella, so there was no one to chase you away anymore. When you arrived you both went to Octavia's room. At first you just kissed and then went to get food, then you watched a movie. You both had a lot of fun and had a good time. After all that, it was late at night and Stolas wanted Octavia to study the grimoire a little so she could master the spells in the book better. So there you were with her watching her do some spells and such until she was about to do a spell that accelerated or reversed time for objects or people. She wanted to make a melon ripen, but due to a mispronunciation, she ended up turning into a child again but retaining her memories.

Octavia: "Huh? "What happened?"

She said before looking in the mirror

Octavia: "I-I'm a kid again, Ryu, don't just watch. Look in the book and see if there's a solution."

She said in a demanding tone, but it only made her more adorable
