When I came to, I found myself reincarnated as Castor, a minor character in my favorite RPG, 'Asteria Quest 7.'

I had a favorite character in this game: Estel, a beautiful swordswoman belonging to a certain party. In the early stages of the game, she was destined to fight Tejat, one of the Demon King's Four Heavenly Kings, acting as a decoy to allow the hero to escape. However, it was a predetermined losing event. Afterwards, the entire party was sent to the Demon King's mining camp as slaves.

To save Estel, my favorite character, I rushed to their side, and somehow, we all survived. However, I was left with a large wound on my back, and I didn't wake up until a month later.

"—Lord Castor! Lord Castor! Lord Castor! Lord Castor! Lord Castor!"

When I woke up, sobbing by my bedside and rejoicing at my survival, was none other than my favorite character, Estel.

"—I'll dedicate my life to you!"

However, by saving my favorite character, I would later come to regret it slightly. That's because her love was overwhelmingly intense—.
