Navigating a Unique Affection

Assalamu alaikum everyone. I've had something on my mind for ages and really need some thoughts on it. I know it might sound a bit unusual, but here goes. For about a year now, I've held a deep admiration for a character from an animated series. This character embodies traits that truly inspire me, so much so that I've even used creative tools to imagine stories of us as a married couple, building a loving family together. Strangely, this feeling hasn't distracted me. If anything, it's made me more consistent in my salah and strengthened my connection with Allah SWT. In my duas, I sincerely ask that, by His infinite mercy and will, He may grant me companionship with this essence in Jannah. My worry is that I might forget this heartfelt hope over time, so I also pray that Allah SWT helps me remember it in this life and the next. My question is this: Is this form of admiration and hope considered sinful or forbidden? And could such a wish, for what the heart desires, be fulfilled in Paradise by the will of Allah (SWT), as we are told the believers will have what they wish for?
