The third season of the hit Netflix queer series "Heartstopper" will air in October.

In an announcement on Wednesday, Netflix said that Nick (Kit Connor) and Charlie (Joe Locke) will face more roadblocks as they try to balance school and their relationship.

"This season, Charlie would like to tell Nick that he loves him. Nick also has something important to say to Charlie. As the summer holiday ends and the months race on, the friends begin to realize that the school year will come with both its joys and its challenges," the streaming platform said.

"As they learn more about each other and their relationships, plan social events and parties, and start thinking about university choices, everyone must learn to lean on those they love when life doesn't go to plan," they added.

Connor admitted that there would be a lot of tension in the series.

"The tension is high. It's like, sexual tension, love, we're all there," the actor said.

Based on the graphic novel of the same name written by Alice Oseman, "Heartstopper" revolves around a gay student Charlie Spring (Locke) who fell in love with his seatmate, rugby star player Nick Nelson (Connor).

The British coming-of-age series received critical acclaim for its diverse representation of the LGBT community and fresh take on queer issues.
