My Little Brother Is the World-Destroying Villain

[Still thinking of a name for the heroine, sob]

The heroine transmigrates into a world where people with supernatural abilities are classified by what they eat.

Her father goes abroad for work and sends her to live with her remarried mother.

On her first day at her mother's house, her mother introduces her to her stepfather and younger brother.

The beautiful boy has snow-white hair and a tear mole beneath his deep blue eyes. Pale and slender, he gives her a shy, bashful smile and greets her first. "Big sister."

The moment they shake hands, the heroine's precognitive ability suddenly activates.

She sees a world riddled with destruction and on the brink of ruin. A white-haired young man sits high atop a grotesque monster, resting his chin in one hand as he gazes down at everything with indifference.

That face belongs to the adult version of the younger brother shaking her hand.

The heroine: Help, my little brother is the villain who will destroy the world!

Su Huaiji has a secret. He was born without emotions. His heart is a black hole, and he can't understand any feelings. He has no joy, anger, sorrow, happiness, or fear.

But he's very smart and can imitate a normal person without a single flaw.

When he was ten, his stepmother introduced him to a girl two years older than him, the daughter of her former husband, who would be staying with them for a few years.

At first meeting: She's afraid of me. Does she know my secret?

Years later: How can I make Big Sister mine?

#The villain no longer destroys the world, but clings to his big sister every day#

[Reader's Notes]

1. The leads are not related by blood and are not registered in the same household. Their romance begins when they're adults.

2. As stated in the blurb, the male lead was born without emotions. His thought processes are unlike a normal person's, and he is cold-blooded and disturbed. If you can't accept that, run and don't look back.

3. Don't mention other authors' works in my comments, and don't mention my work in other authors' comments.

Theme: Love can change a person.
