In a recent interview with The Hollywood Reporter, writer of the show Brian Yorkey explained that there is more of Hannah's story to tell.
"One of the things that is a fundamental element of our show is the weaving of past and the present. Hannah's story is still very much not finished. She's an integral part of whatever the next chapter of the story is, and she's very much still at the centre of it."
There is so much the show can go on for season 2, as the first left with many cliffhangers, aka, Alex Standall's suicide attempt and Tyler's intent with all those guns...
Katherine Langford, who plays Hannah, also told THR that, "It would be cool to continue the dialogue of this story. There are so many cliffhangers at the end of the season."
Although Netflix said in a statement that they "can't confirm anything at this time," we are pretty sure it'll happen.
