Then, in the coming days. The hero’s parents, the heroes of the past, the first love, the princess childhood friend, the geniuses of the era, and the world will tremble.

“Shinyama Minato-kun…! Will you make me your bride, please?” Hanae Riko, the most beautiful girl in the school, proposed to me, and before I knew any better, my newlywed life had already begun. My wife was so cute as she always happily follows me around every day and doesn’t want to leave my side even for a moment. She always does all the cleaning, laundry, cooking, sewing, and other household chores like a pro, and her skills are flawless. In addition, she was extremely devoted to me. “I’ve made a fortune in investments so that Minato-kun can play and live for the rest of his life. Use it as you like!” This kind of overzealous service regularly occurred. And I couldn’t help but think it’s adorable how she wagged her invisible tail so wildly whenever I gave her a single word of praise. Yes, in front of me, Riko was like a small dog loving its owner too much. But don’t be conceited. This was a contract marriage. Riko was not in love with me. – When I had finally asked her why she was still so devoted to me despite being under contract, she puffed out her cheeks and responded. “Minato-kun, you’re too cautious about the proposal…” Eh… so it’s fine for us to get married under contract…? This was a love story that started with a marriage at day zero and was just a happy, one-sided love story.

Eliza Kaldia, who reincarnated as a noble girl villainess in a fantasy otome game, was stuck in a world that seemed far from her image of how noble girls should be living, as the fated events of the game were still far off while she remained a child. In the first place, it was suspected if she could even live to make it to the school setting of the game. Due to changes in the situation of the neighboring country which never appeared in the original game, the world became nothing like the flowery school life from the game. It was a world where even young girls had to take up weapons. How did it turn out this way… I don’t have any cheat-like abilities. I can’t use magic. Though, my sense of ethics might have become a little twisted due to being reincarnated.
