Pain Syndrome

A gloomy, possessive yandere brother x a bright, sunny girl

1.

When Liang Mucheng was thirteen, his father remarried, and he gained a stepsister two years younger than him.

Liang Shunyi was lively and carefree. She barged into his cold, dark world like a bandit, patiently nurturing him and taking meticulous care of him.

Liang Mucheng took it upon himself to provide for her in every way, dutifully fulfilling his responsibilities as her older brother.

Until one not-quite-dawn, he woke from a dream.

The sticky sensation on his hand sent him into a panic. He shoved the bedsheets into the washing machine, only to run into Liang Shunyi as she got up.

"Big brother? Why are you washing the sheets so early?"

Faced with the girl's question, Liang Mucheng said nothing.

How could he answer?

Should he tell her that the devoted, attentive big brother had done such "wonderful things" to her in his dream?

2.

His parents divorced, and the Liang family went bankrupt. Liang Mucheng rented a tiny apartment and brought Liang Shunyi to live with him.

He wouldn't let her get a job or make friends, selfishly keeping her confined within his control.

On the day the college entrance exam results came out, Liang Shunyi came home reeking of alcohol, escorted by a classmate.

Faced with a handsome male classmate from a wealthy family, Liang Mucheng experienced the meaning of failure for the first time.

"You like him, don't you?" Inferiority tore at him. "Then what am I to you?"

Liang Shunyi poked his chin. "You're my big brother..."

"Just your big brother?" He licked her fingertip. "Would a big brother do this to his little sister?"

Drunk with youthful abandon, the girl pressed her first kiss to his neck, daring to touch what was forbidden.

After the moon had crossed the sky, Liang Mucheng carried Liang Shunyi to the bathroom and scrubbed her palm clean.

"Good girl. You did so well."

He was a filthy thief, stealing the kiss he'd reenacted in his mind hundreds and hundreds of times.

And the unfinished dream of their unabashed, mutual descent into desire.

2. They are not on the same household registration. Their romance begins after their parents divorce.

3. The male lead becomes psychologically twisted midway through the story.

4. Reunited after years apart. Two love-crazed people, with a touch of coercion.

5. The "Family" arc is told in flashbacks; the "Lovers" arc covers their reunion.

Theme: Eat well and sleep well.
