After Transmigrating into a Book, the Idle Empress Dowager Is Anything but Idle

[One True Pairing + Transmigrate Into a Book + System + Food + An Unrealistic Setting With No Logic]

Modern-day movie star Bai Tanyue transmigrates into a novel she barely read and becomes empress from the start. Before long, the emperor dies, and she rightfully becomes the empress dowager, reaching the very pinnacle of a woman's status. Even the newly enthroned emperor has to bow to her. She can eat, drink, and enjoy herself in the harem however she likes, but what can she do when the System keeps making her meddle in other people's affairs and play the good Samaritan?

Male lead's perspective: The first time he meets his father's young empress, he thinks she's all looks and has impure intentions. The second time, he thinks she's frivolous... By the Nth time, he can't believe she can ignore him and treat him so coldly!

A tsundere emperor who can be sweet or fierce and talks himself into falling for her VS a little empress dowager who uses her beauty to get her way and has no idea how flirtatious she is

Content warnings: The main couple are exclusive to each other, but the male lead will have concubines in name only later on. The setting is entirely fictional, with many original details, and the logic serves only to move the plot forward. The pacing is not very fast. Many people will like the leads, and there will be familiar melodramatic tropes. Aside from the main couple, the side couples may have some angst, so if that's not your thing, please don't click in.
