『She’s always putting on that grumpy face even though she’s not actually that upset! Oh, why can’t she just be honest with herself…!?』

『She is a tsundere, after all? When her embarrassment levels exceed a certain limit, she will explode into anger. However, the point that she’s suppressing under the surface is that she wouldn’t mind that sort of thing if it were in a less public place.』

As Endo-kun passionately reacts to the antics of Lady Liselotte, the villainess of an otome game, Kobayashi-san provides a painstaking breakdown of her tsundere behaviour.

Suddenly, one person could hear their voices; Liselotte’s fiancée, Prince Siegward.

That is where this story begins.

"Ah… Ahhhhhhhhhhh!"

The one who's become the Crown Prince's fiancée is the Duke's daughter Serea, but during their first meeting, she screamed and collapsed! Had she remembered something from her previous life?

Isn't that right~ An "event" and those "program settings" have no connection to me though. Let's go back to my place and I'll slowly and sweetly make you fall desperately in love with me!

This otome game's villainess is going to follow a harsh path, and will fight to change her fate.

Taken from Baka-updates: Yuri Shibuya was living a pretty normal life. That changed the day he was dunked into a toilet after an attempt to save a classmate from a gang of bullies. Instead of just getting a good soaking, he's pulled in. The next thing he knows, he's in a world that vaguely resembles medieval Europe. If that's not odd enough, he's told that he is to be the next Maoh, just because he has black hair and black eyes. The Maoh is the King of the Mazoku, who are coexisting not-so-peacefully with the humans in this world. Much to his subject's dismay, he's totally different from the rulers they're accustomed to. He's kind, considerate, a believer in justice, and not willing to use violence to solve conflicts. Not exactly someone they want running a country on the very brink of war. Now, Yuri has to deal with trying to become a good Maoh, while at the same time attempting to adapt to this land's customs and culture, all in a world where the tension between the humans and Mazoku is reaching its peak.

“Why don’t you give me the honor of escorting the Princess?”

I have had enough of dealing with my father, so why did an unexpected character suddenly appear? What if this person disrupts my plan?
