Bittersweet sits between HE and BE: someone may be lost, but those left behind keep moving; love may not survive, but a character grows into themselves. To earn the Bittersweet tag, a book must let the reader feel both the loss and the gain at the final page — not pure tragedy, not pure resolution.
This is the right shelf for readers who want emotional realism — neither cured nor crushed. Touchstones include Norwegian Wood, The Song of Achilles, Pachinko. Each card shows roughly how much sweet vs. bitter the book leans, and which specific triggers will hit hardest.
