But, with the first, there was a book to follow. For the second season, show writers are paving a new path, and co-producer Selena Gomez has seen some of their work.
During a recent chat with Seattle's Movin' 92.5 radio station, Selena revealed that, "I'm so excited for season 2."
Um, same. Duh.
"I think it's going to be so exciting because I didn't expect the first to be as loud. I didn't expect it to have the reaction that it did. It was amazing, and it was complicated, and there was a lot of stuff that came with it, and I understood what that meant," she continued.
But there is one particular story line for the next season that Selena is already freaking out over...
"I was in the writers' room the other day and they're working so hard and it's going to come together. I was sitting there at the table, like, 'Wait, what happened?!' Almost like freaking out." OMG.
There are so many things that it could be, we wouldn't even know where to start speculating.
She did however reveal that it will continue to delve into the other side of Hannah's story, and how she could have been an unreliable narrator.
"I think for season 2, we elaborate more on some of those questions and the stories and the resolution if you will of what some of these kids have gone through so - and are going through.
"I'm excited. It's going to be great," she said.
The cast is returning to the show for the second season, but casting is current underway from some ~fresh~ faces too.
KEEN!
