A cheerful story overall, with a timid, laid-back heroine x a male lead who embodies righteousness.
Here's the serious blurb:
The immortal artifact Luoguang awakens and discovers that she is actually the villainess in a romance-targeting novel.
Huh? Are you kidding me? How could an immortal artifact like me be a villainess?
Luoguang falls silent for a moment, then takes a closer look. It turns out it's because her contracted partner, the Demon Lord Jiang Linfeng, is the most wicked and alluring one in the heroine's harem. As his contracted partner, Luoguang naturally gets in the way of the heroine's conquest.
The Demon Lord Jiang Linfeng has cultivated demonic magic for years, and something has gone badly wrong with his cultivation. Simply put, he goes mad for a few days every month.
To win the Demon Lord over, the heroine feeds him her blood and even cuts off her own flesh, but neither works half as well as Luoguang's zither. Since the heroine's efforts aren't paying off, Luoguang naturally becomes a stumbling block on her road to winning him over!
Luoguang: ??? I'm a soothing, healing immortal artifact. Your blood and flesh don't have any healing properties.
Later, the heroine finally manages to get herself killed. Only after she dies does the Demon Lord belatedly realize that he's fallen hopelessly in love with her.
So poor Luoguang has her spirit extracted and her soul torn apart by the Demon Lord to bring the heroine back to life. Thanks to the protagonists' enormous, overwhelmingly powerful plot armor, the heroine is successfully revived, while Luoguang's soul scatters and she vanishes from the world.
Luoguang: "..." I would like to opt out of this melodrama.
Theme: Building a wonderful world together.
