Jackson Finch

Jackson Michael Finch is a main character in Post Millennials. He is an aspiring musician studying at Illinois University while teaching music lessons on the side for guitar and piano. He graduated from Eleanor Roosevelt High School in Time For Me To Fly. He spent most of high school balancing his schoolwork with his family life and developing close friendships.

Jackson grew up in an extremely complicated environment. He was raised by his father for years until all of a sudden he left the kids in search of Jackson's mother. As a result, Jackson's older brother Jonas Finch was left to raise Jackson and his sister Sophie Finch all alone. This led to Jonas seeking money in all of the wrong places, including lots of robberies. This eventually landed Jonas in jail. Prior to this event, Sophie was taken away by child protective services. As a result, Jackson spends a lot of his time at the beginning of the series reaching out and trying to reconnect with Sophie while Jonas fights to get out of prison. Jackson and Jonas eventually make amends as well, although it does take a long time.

Jackson develops several complicated romantic relationships throughout the series. His primary love interest is consistently Keltie Reid, although he is often forced to fight for her with other contenders. In addition to Keltie, Jackson has brief romantic relationships with Ana Jalil, Mia Albright, and Mallory Forbes, however his love life revolves almost entirely around his relationship with Keltie.

Friendship is very important to Jackson, especially at the beginning of the series when he isn't ready for any romantic conflict. He quickly becomes close friends with Keltie, Ana, and Dylan Fisher. Despite Ana and Dylan having a crush on Jackson, this friendship continues for a long time. Eventually, through baseball, Jackson becomes close friends with Nate Saracen. The two develop a love-hate relationship based on their conflict over Sophie. Jackson hates Nate for a long time for dating his younger sister.

Jackson attempts throughout the series to avoid conflict, but often finds himself involved in heated battles with the other characters. His most aggressive rivalry forms against Austin Matlock when they're fighting over Keltie.

He is portrayed by actor and singer Shawn Mendes.
