I'm not sure specifically which 'la gata full story' you're referring to. It could be a story about a cat (gata means cat in Spanish). Maybe it's a local folktale or a personal narrative someone has created.
Toge Inumaki is important too. His special cursed speech ability makes him stand out. Also, the principal of the school, Masamichi Yaga, is likely to be important as he is in a position of authority and has an influence on Gojo and the other students. There could be other characters like the members of different clans that also play roles in the complex web of the story.
As I'm not aware of the 'la gata telenovela' details, we can only guess. It's likely that the main character is the 'gata'. She could be a young, independent woman.

I haven't watched 'la gata telenovela' so I can't provide the exact full story. But in a typical telenovela story, there are often complex relationships.
