Heartstopper has returned to Netflix for season 3, and with it, no declaration that this is either the final season or season 4 is coming. Why? Because it’s complicated, and is likely to come down to the source material.

Being a show adapted from a graphic novel, Heartstopper sure has a lot of books in it. Each season of Alice Oseman's Netflix adaptation sees fierce bookworm Isaac (Tobie Donovan) flaunting consistently excellent reading taste, and each character always has a bunch of noteworthy books on their shelves or in their backpacks.
