Season two of Heated Rivalry is set to be "much more serious".
The sports romance show, which is based on the Game Changers book series by Rachel Reid, proved to be a huge hit with viewers during season one, and Jacob Tierney - who created, wrote, and directed the first season - has now teased the upcoming episodes, explaining how the programme will evolve.
Speaking at New York City for BookCon, he shared: "It really is different, and the challenge, from an adaptation standpoint, is you're in much more serious territory.
"There's still lots of flirting, and there's lots of sex, but it's this kind of danger. This kind of 'hotel room, adolescent sex' stuff is largely gone."
Hudson Williams and Connor Storrie are both returning for season two of the show, and filming is set to begin over the summer.
The Long Game, the book that inspires the second season, picks up a decade into their relationship, and explores the challenges of an adult romance.
Jacob explained: "What do you do after the rush of danger is gone and yet now you have to live in a relationship where you still aren't communicating properly, much as you would like to?
"You can say you love each other, but as adults know, there's so much more than that to make a relationship successful. And that is what they're learning."
Jacob even hinted that The Long Game could be split across two seasons.
He said: "It's a lot of book."
Meanwhile, Connor previously confessed to being shocked by the show's success.
The 26-year-old actor - who plays Ilya Rozanov on the show - told Interview magazine: "It’s been shocking because I’m a nihilist when it comes to how I think things are going to be received. There’s so many things that get made, and online we have access to so many opinions that I fully prepared myself before anything happened.
"I mean, it sounds negative, but I really don’t mean it as a negative thing. I actually think it’s really beautiful and realistic and gives your work an unconditional love if you can go in accepting the worst case scenario like, 'Guess what? I’m going to do it regardless.' I was fully prepared for nothing to really come of this."
