No you're obsessed with it because you have mental issues. Healthy people watch and enjoy shows, but unhealthy people set that shows protagonist as their avatar, make thousands of the same model, constantly nitpick about small details relating to the show.
It's exhausting. "It's a good show therefore I have the right to be obsessed" is just trying to justify your weird unhealthy behavior. If you want to see a normal person, look at pompmaker. He liked Doraemon but it's not the center of 100% of his dialog.
