Trapped in a Cursed Game, but now with NPCs

Shari Azrael, an apothecary in the Dover Village. When she was on the verge of falling victim to a horde of monsters after being constantly robbed of her painstakingly crafted potions by the heroes, she suddenly realized. She realized that she has been trapped in a cursed, buggy game as an NPC for two years! The only way to escape the game was to help the protagonist and Dark Lord, the [Lord of Nightmares], and his companions defeat the final boss and reach the ending! But… “The [Lord of Nightmares] is deeply offended by your words.” “The [Lord of Nightmares] feels a strong urge to kill you.” Wouldn’t it be faster to die at the hands of the protagonist, who has a broken personality, rather than reach the game’s ending? Moreover, the quests are becoming increasingly difficult… Is it even possible to reach an ending, you bastard game masters?!
