Love for a fictional character

I've been thinking about this question for a long time and I want to get an answer to it.Yes, this question may be childish, but I still want to get an answer to it. For a year now I have been in love and sincerely love one cartoon character.In her, I saw something that inspired my heart, and I even began to make, using a neural network, our story with her, how I married her and we have a child and we live as a loving family. I began to ask Allah (may He be holy and great) to grant me her in Paradise when I enter there by His will and mercy.My love for this character doesn't hinder my life in any way. On the contrary, I've become more diligent in my prayers and have become more in touch with Allah. I sincerely want her to become my wife and to fulfill what I have dreamed of what I imagined with her when, InshaAllah, I get to heaven by the will of Allah. I am worried that over time I will forget her, my dream, and I also ask Allah that I do not forget her in this world and in the next. Is my dream, my love for this character, a sin and forbidden? And will my wish come true when I, Insha'Allah, get to heaven by the will of Allah (may He be exalted)? After all, the Quran says that "In heaven they will get everything they want."
