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

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?

Ekaterina has settled well into her new life as the not-so-villainous villainess of an otome game. Perhaps a little too well, in fact! On top of spending most of her time thinking about her dear brother, she’s become friends with the heroine, Flora, and the main love interest of the game, Prince Mikhail, whom she’d sworn never to approach. Ekaterina’s not too worried, though, because she’s on track to avoid the doom flags that threaten her family and the empire after successfully driving back the monster that attacked the academy. She’s ready to kick back and take it easy when Alexei drops a bomb on her: the imperial family is about to visit their residence. How is she supposed to prepare for that?! Not to mention, she has to deal with her grandmother’s remaining supporters and her first-ever exam season in this world! Forget about relaxation, Ekaterina has no time to spare!

After her quest for the perfect gift for Alexei’s 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 duchy’s 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!

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...

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 long summer vacation has finally come to an end, and Ekaterina, her beloved brother, and their friends—Mikhail and Flora—are back in the capital for the second semester. After school kicks off and Ekaterina reunites with her classmates, her friend Marina has a genius idea: They should organize a musical evening where everyone can showcase their talents! As a former choir girl, Ekaterina is more than happy to take charge. Her preparations for the event lead her to make the acquaintance of a classmate of theirs named Renato Selesar, a prickly yet adorable boy with an unbelievable talent for music. At the same time, tensions start rising between Ekaterina and Lydia Selesnoa—the daughter of a powerful marquess—who has her sights set on the empress’s throne. It appears Ekaterina’s recent closeness with Mikhail hasn’t gone unnoticed...

Ekaterina and Lydia’s dramatic showdown ended in a resounding victory for Ekaterina and her allies. Now, Lydia has changed her mind about becoming empress, while Olga and Renato bask in glory after being honored by the God of Music himself. However, peace is short-lived at the Magic Academy—buzz is already building around the long-awaited school festival, which Ekaterina remembers as a pivotal event in the game’s path to Mikhail’s heart. Then again, Ekaterina couldn’t care less about romance routes. Her focus is on two things: avoiding any doom flags that still loom over her, and ensuring her beloved brother enjoys the festival without overworking himself. To see Alexei smile, our favorite villainess is ready to stop at nothing! But in the background, other schemes are unfolding that Ekaterina can’t begin to imagine, and she certainly hasn’t seen the last of those who oppose the Yulnovas...
