Firefly Lane's final trailer promises emotional ending for Kate and Tully

Firefly Lane fans are already in bits over the show's finale after Netflix released the series' last ever trailer.

It didn't take long for fans of the show to binge-watch their way through all nine episodes of season two of the series which is based on Kristin Hannah's novel of the same name and sequel Fly Away.

However, viewers may regret not having dragged out their watching for a longer period of time, now only left with part two of season two - which has been confirmed as concluding the entire series.

The series stars Katherine Heigl alongside Sarah Chalke - the duo playing the roles of 30-year long best friends Tully Hart and Kate Mularkey.

Part one of the second season sees Kate diagnosed with an aggressive form of breast cancer, quick to go to Tully's apartment to tell her only to discover her best friend has left.

The official Netflix synopsis for part two of season two reads: "For Kate and Tully, no obstacle is too big when it comes to their lifelong friendship. But is there one mistake that could tear them apart forever?"

Fans already can't hack the emotional ending to the series they know is coming.

Flooding to the official trailer on YouTube, viewers of Firefly Lane have already been reduced to tears by the series' final trailer.

"You know a trailer is good when it makes you cry," one user wrote.

Another said: "I have a bad feeling that the series will end very sad and emotional. I think Kate will die and Tully crying beside her bed saying, 'Please don’t go don’t leave me I need you'."

"Can't wait for the last episode. I cried watching this," a third commented.

A final resolved: "I'm so excited. Wait a minute did they say final chapter. Now I'm having mixed emotions. Firefly Lane is such a warm, humorous feel good show. It's just what we need during these hateful times.

"Season two part two is giving me the movie Beaches vibe. On top of it they're playing Abba's Dancing Queen song in the background from Mamma Mia. I felt so sadden for Tully when Kate carried her grudge against Tully. It was too long. I grew up in the same days as Tully and Kate. I had the same kind of friendship with my friend Sheila and to this day we still remain friends.

"I'm hoping that Firefly Lane gives us a happy closure."

Part two of the second - and final - season of Firefly Lane is currently set to premiere on Netflix on 27 April.

The streaming service teases: "Tune in to [...] find out out how Kate and Tully’s story ends - even if a friendship like theirs lasts longer than a lifetime. Firefly Lane girls forever!"
