Popular Netflix series ‘On My Block’ is set to return for the fourth and final season on the streaming platform as we get ready to bid adieu to our favorite characters. The show revolves around a quartet of bright, street-savvy friends who are navigating their way through high school.

The upcoming series joins the list of titles that are led by Black actors. ‘Pose’, ‘Lupin’ and ‘Dear White People’ are some of the finest examples of the projects led by brilliant Black actors. The ending of Season 3 saw all the main characters as they move forward in their lives. In the end, we saw an epilogue that gave us an idea that distance has indeed separated them and they are not a part of each other’s lives.
