Toaru Majutsu no Index - Volume 2, Chapter 4: The Deadly Seven. Deadly_Sins.

In a realm where even the faintest shadows whisper untold tales, I came to realize that the forgotten often hold the most powerful narratives.As an avid admirer of the world's most beloved series, I never imagined that one night's rest would pull me into its very fabric.“Why on earth am I stuck in this world? And why, of all people, am I him?”I had become Arthur Nightingale—Class A’s most unremarkable student. A magic swordsman barely worthy of mention, ranked 8th among the first-years. A mere footnote in the grand story.Still, with this body’s abilities and my own insider knowledge, I figured I could carve out a peaceful life. Or so I believed.“This was the only way,” the voice repeated, resolute. “The only way to stop her.”Little did I know how truly unique Arthur Nightingale was—or the path this journey would force me to take...

After the death of Fu Sinian, Yu Duo’s heart shattered into pieces. As his widow, she was the recipient of Fu Sinian’s massive amount of inheritance. She spent her days drowning herself with alcohol and was depressed all the time. She mourned her late husband with the companionship of her designer purses, designer jewelries, and money that could last her several lifetimes.

But only Fu Sinian knew the truth — that after his death, this woman hosted parties, lived in their mansion, drove expensive sport cars, traveled the world, and flirted with men. She was having the time of her life.

Fu Sinian wasn’t so angry that his soul dissipated; quite the contrary, he was so angry that he had come back to life!

Fu Sinian, who had come back to live, looked at the mourning Yu Duo and smiled devilishly.

“We are on! Watch me make you fall in love with me for real this time!”
