無能な害悪公爵令息とバカにされている事に前世の記憶を思い出し気付いた俺、婚約破棄された元婚約者を助けた次の日から元婚約者の視線を感じるんだが？

My magic skills are below average, my swordsmanship is below average, my academic knowledge is below average, and my pride is above average. With the power of being born into a ducal family, I’ve lived as I pleased, silencing anyone who acted arrogantly toward me and securing a fiancée through my family’s influence.

I dislike effort and studying, so my skills in magic, swordsmanship, and academics are honestly the lowest in the academy. Ignoring this reality, I compensated for my shortcomings with my family’s power, acting arrogantly.

If that were all, it wouldn’t be so bad, but I genuinely believed these were my own abilities, making me an irredeemable scumbag.

That was me.

Then, I remembered the memories of my past life and, looking at myself objectively, realized I was a scumbag. I deeply regretted my past actions. At the same time, I remembered that in my previous life, I lived in a world where magic and science were more advanced than this one, and I had died in battle as a national mage in one of the advanced countries.

I tried using the magic I had wielded in my previous life and found I could use it without any problems. I also discovered I could use the storage I had used in my past life, along with the advanced scientific and magical weapons and armor stored within it.

Moreover, I found that my account with the major online store Am**on was still active and accessible through the storage.

With this, I should be able to manage in this world.

One day, during a dungeon exploration class at the academy, I got caught in the rare event of the dungeon evolving, leaving only me and my former fiancée trapped inside. I couldn’t abandon her, so I promised not to reveal my abilities and helped her. Since that day, I feel like my former fiancée has been looking at me, but is it just my imagination?

For now, I’ll use the storage from my past life and leverage the major online store Am**on and AI-powered robots to heal broken s*aves and aim for a slow life with the knowledge from the AI.
