“Heartstopper” season 3 is coming in October, Netflix announced Wednesday, March 20.

Series creator and writer Alice Oseman said the third installment of the show would revolve around the depth of Nick (Kit Connor) and Charlie’s (Joe Locke) relationship, which includes the latter’s mental health issues.

“Season 2 ended with Nick beginning to understand the extent of Charlie’s mental health issues, and it’s this that will drive the story through Season 3,” Oseman told Netflix.

Oseman said she was “excited” that the show’s tone matures with the characters who are also growing up.

“Mental health, sex, university ambitions, and more: Nick, Charlie, and the Heartstopper teens are getting older, learning more about themselves and each other, and experiencing new desires, new fears, and new joys as they approach adulthood,” she continued.

Netflix released a teaser for the upcoming season, showing the behind-the-scenes of the actors and their thoughts on their respective characters.

Meanwhile, “Bridgerton” star Jonathan Bailey has been rumored to appear as a guest in the third season of “Heartstopper,” where he would play the character Jack Maddox.

“Heartstopper” follows the love story of teens Charlie Spring and Nick Nelson as they navigate love, friendship, mental health, and identity.
