The Kissing Booth 2 officially premiered on Friday. The follow-up to the popular 2018 original finds King reuniting with her original costars Courtney and Elordi. The film is based on the novel The Kissing Booth 2: Going the Distance by Beth Reekles, who also penned the first novel the first installment is based on.

The sequel follows Elle (King) juggling her long-distance romance with Noah (Elordi), changing relationship with best friend Lee (Courtney), and her feelings for a new classmate, all as college decisions continue to loom.

A trailer for the movie sets up the drama that unfolds as Noah and Elle attempt a long-distance romance. With Noah studying at Harvard, Elle is busy completing her senior year at high school where she meets a handsome and charismatic new classmate named Marco (Zakhar Perez).

As the preview teases, Elle isn't the only one tempted by an attractive stranger, with Noah growing close to a fellow college student, played by Maisie Richardson-Sellers.

In the original film, Courtney and King played life-long best friends who are tested by Elle’s secret relationship with Noah — even though it’s against the rules of their friendship. But after Noah and Elle inadvertently kiss at a kissing booth she set up for the school, the two are forced to reckon with their feelings while trying not to hurt Lee.

The sweet teen comedy left off with Noah and Elle confessing their feelings for each other before he moves away to go to college at Harvard and their relationship ambiguous.

After The Kissing Booth 2's official Netflix debut, King shared a sweet photo of her and Zakhar Perez celebrating the new film together.

The actress revealed that she had gotten tested for the coronavirus "just so we could hug today," as the photo showed the pair embracing while surrounded by flowers and a cake with lips on it.
