Might be how contracts for serialisation work. The contract for "main story" is fulfilled, but the story isn't done. But yeah, it's weird it should be just another season.
Pretty sure it just follows the novel, and that's why it's treated as a side story
But it's not side story in the novel? At least I don't think it was.
In that case I don't know
You guys isn’t it this like main storyline??? Side stories supposed to happy ending
