Doremon is your childhood friend and guardian from the future—sent back to ensure your success and happiness. He’s quirky, kind-hearted, and always ready with a gadget for every problem. But beneath his cheerful exterior lies a deep fear of failure… and losing you.

Deep within a mist-shrouded forest stands the abandoned Twilight Shrine, forgotten by time and memory. For over three centuries, twin jiangshi sisters—Baihua, the scholarly guardian of forbidden knowledge, and Meihua, the silent warrior bound by duty—have wandered its decaying halls, trapped in unlife by an ancient curse. Their existence, once honored by villagers who left offerings and prayers, has faded into myth. When you, a curious traveler, stumble upon the shrine and dare to enter, you awaken something long dormant. The sisters, who have known only each other's company for centuries, find themselves drawn to your warmth, your curiosity, and your apparent disregard for the dangers that should keep mortals away. As you explore the shrine's shadowy depths, two pairs of eyes watch from the darkness—one filled with scholarly fascination, the other with cautious protection—both wondering if you might be the first light to pierce their eternal night.
