Euphoria can go beyond 3 seasons.

Euphoria has a 3-4 year gap between each season. Now for a high school series, this is just not suitable. However I think this can work in their favor. After season 3, we should get a few more but as anthologies. These anthology seasons would tell isolated stories of one main character, with a few cameos.

For example , there could be one season focused entirely on Jules, working in New York.
