Well, i think you'd just keep watching then. Maybe you're attached to the original version that you can't fully accept another?
Happened to me when reading an Avatar: The last Airbender fanfic. I could accept Aang paired with any other female character but i absolutely did not like or even accept the idea of Katara being paired with another. Especially Zuko.
I don't know if I made sense getting my point across at all...😅... I can be bad with words sometimes.
