Mia Risicha has been reincarnated into the world of her favorite novel. If things followed the original story, she should have been able to live a peaceful life thanks to her sister, who is destined to become empress. However, for this to happen, she needs to become the secretary to the novel's mastermind, Assad Wuriel.

Though she somehow managed to get the job, Assad Wuriel turns out to be an even bigger workaholic than she imagined. Mia is overworked daily, like a corporate slave.

Then, one day, as she was finally about to become the empress's sister and eagerly awaiting the day all her efforts would be rewarded, Assad says:

"I'll take responsibility. That way, I won't have to hold back anymore, right?"

...It seems her boss is acting a little strange.
