The main character is reborn as a character of a game he played in his previous life. This character falls into ruin along with the villainess, spending the last of their years together, a man named Kururi Helan.
No details of this are written inside the game, it can’t be understood why this sub-character ended up with the villainess. However, that is of no importance.
Living as a needy farmer along with someone is unpleasant, so the main character seeks a profession. For now, he aims for becoming a blacksmith as he originally had skill in it.
