Goodbye, Overtime! This Reincarnated Villainess Is Living for Her New Big Brothe

Yukimura Rina is an overworked twenty-something systems engineer who's dangerously close to her breaking point. Her only comfort is an otome game with a charming side character, the brother of the villainess, who soothes her weary heart. She gets so hooked that she forgoes sleep and ends up blacking out...only to wake up inside the game as the villainess, Ekaterina. She's now the little sister of her favorite character! Her new brother Alexei is handsome, kind, and responsible-the whole package. Rina, now Ekaterina, would be happy just staying by his side, except for one little problem. If she allows the game to run its course, she and her brother are headed straight for a terrible future! Can Ekaterina overcome the doom flags that threaten her new family and the empire, while also preventing Alexei from working himself to death?

Between the celebratory banquet and the mountain pilgrimage, Ekaterina and Alexei's summer vacation has been very eventful, and yet it's far from over! The heroine of the game, Flora, and the main love interest and crown prince of the empire, Mikhail, are finally visiting the siblings. Ekaterina has been hard at work and has planned a series of exciting events for them to enjoy during their stay. The first is a welcome banquet, and she has everything planned to perfection: The prince and the heroine, whom she expects have grown closer on the way, will share the first dance. Ekaterina can't wait to watch their love blossom-but then Mikhail requests her as his partner for the first dance. The chaos only continues from there! Are the doom flags Ekaterina has so deftly dodged coming back to haunt her?

The eventful celebratory banquet is finally over, but that does not mean Ekaterina and her dear brother, Alexei, have any time to unwind and enjoy their summer vacation after triumphing over the hateful Novadain. Running a duchy is hard work, and Alexei has much to do-so much, in fact, that he finds himself struggling to squeeze a very important pilgrimage into his tight schedule. Something has to be done lest the family earns the ire of the mountain gods, and Ekaterina is not about to stand aside and watch her brother kill himself with overwork. That means it's time for this not-so-villainous villainess to make herself useful by running her first errand! Ekaterina gladly embarks on her journey, eager to learn more about the Yulnova Duchy, but what dangers and discoveries await her along the way? The roads of the duchy are sure to hold many secrets...

After her quest for the perfect gift for Alexeis birthday led her to purchase a glass workshop, Ekaterina must now learn how to manage a company. She has no intention of letting her new business weigh on the duchys finances and is keen on turning a profit by making the glass pens from her past life sell like hotcakes among the rich and powerful! Since summer vacation is coming soon, that should provide her with all the free time she needs...or will it? When Alexei and Ekaterina return to their main residence in the Yulnova Duchy for the holiday, their trip home may prove more eventful than they expected!
