A man who lost his wife and child in an accident ended his own life in despair, choosing to follow them. However, when he woke up, he found himself possessing the body of the father of the final boss from a game he’d played as a child. In the original storyline, this father had abused his daughter, which led her to become the final boss out of deep resentment.
But this man could never bring himself to treat his new daughter cruelly. Determined to make her happy, especially after losing his daughter in his previous life, he worked tirelessly for her. Alongside his main job, he explored dungeons and gave his all to ensure she could have an easy life, even making it possible for her to attend school.
As a result… she never went down the dark path, nor did she become the final boss. However, she developed an intense attachment to her father.
