Toaru Majutsu no Index - Volume 6, Chapter 3: Closure. Battle_Cry.

This is a therapeutic romance novel that mixes psychology and science fiction.

Lin ShuYi was sentenced to death by the traitorous Emperor for a treasonous crime he didn’t commit.

[Hiddenidentity, Femalelead, Loveaftermarriage]She originally planned to take her sister's place and marry a 60-year-old man, but accidentally married him, who was the richest man as he had also made a mistake. She thought they would soon divorce, but he chose to temporarily maintain the marriage.The public disliked her because of her ordinary background and believed that she was not worthy of him. However, her multiple identities were gradually exposed: academician at the National Research Institute, a brilliant doctor, the racing god, national representative of Go, and gold medalist in figure skating. And when the world found out that their marriage was only contracted for one year, she garnered numerous suitors. “Get out! We will never divorce! Never and ever!” he declared.

Grandpa Yu often repeated beside the ear of Yu Zhen, saying that he(YZ) has a soul in his body. If he doesn’t properly train in asceticism, and raise then send away the powerful soul, in this lifetime he would have to live as a bachelor.

After some years, Grandpa Yu passed away and a cold-faced handsome guy came to his door in a luxury car – with a household register in his hands.
