From Master Assassin to a Random Extra: OP in a Dating Sim - Chapter 19: The Unnatural Instructor

There is always such a person in the world who likes to take their ex/Bai Yueguang/best friend as a stepping stone for their love.
These exes/Bai Yueguang/Girlfriends are called female supporting roles. They obviously did nothing. Just because they were involved with the male and female protagonists, they were trampled on, hurt, and even left a shadow that will never go away for a lifetime.
Jiang centrifugally felt sorry for those innocent girls, so he traveled from one world to another to help them cross that hurdle.
However, after a certain world, the mission is obviously wrong.
Jiang Li: “I will treat you well.”
“It’s not enough.” The girl imprisoned Jiang Li in her arms, breathing warmly: “Don’t leave, you must always be good to me, only to me.”
Jiang Li: ? ? ?

- Description from novelbuddy

After an accident leaves him hospitalized, Mr. Yu awakens to an environment where pleasure and power flow unchecked. The hospital transforms into a stage for relentless sexual encounters nurses, patients, and even visitors engage in acts that dissolve the lines between caregiver and lover. Mr. Yu, both participant and object of others' desires, quickly becomes central to an unfolding erotic drama. The cast includes assertive nurses like Qianqian and Yunxin, whose care crosses into sexual service, a fellow patient eager to join in, and a revolving door of visitors whose own needs intertwine with Yu's recovery.The narrative expands to Mr. Yu’s life as a high school teacher. His homeroom class, especially the charming and voluptuous Lin Keke, develops cult-like devotion. Here, “consent” is reimagined through the lens of local customs and laws, and students openly form sexual, emotional, and ritualistic bonds with teachers and classmates. Lin Keke’s quest to become Mr. Yu’s sex slave supported by her similarly uninhibited family provides both tenderness and transgression, with familial relations redefined around sexual and submissive acts.Throughout, the protagonist grapples with societal expectations, guilt, and temptation, all while cultivating close ties sexual, emotional, and psychological to those around him. The world is painted as an alternate reality where sexual agency, devotion, and hierarchy coexist, but ordinary norms are replaced by personal rituals and acts of submission, love, and erotic exchange. Explicitly exploring taboo themes through detailed character actions and thoughts, the novel unfolds as an uncensored fantasy of intimacy, dominance, and vulnerability.NTR, Netorare, Adultery, Group Sex, BDSM, Humiliation, Sex Slave, Sex Toys, Incest, MTR, Married, Cheating Mother, Seduction, Objectification, Infidelity, Domination, Sexual corruption, Free Use

She killed his wife, destroyed his reputation, and ran off with his son. 8 years later, she returned home with her genius son, who already had a fiancée. “Give me the child, or you can’t afford the price.”“A girl who eats meat and vegetables doesn’t suffer, if you want a child, find yourself a woman to give you one.”

“….Krische-sama, are you not afraid of killing people?”

“……? No. After all, it doesn’t hurt Krische.”

Although gifted with the talent to do anything with ease, the girl lacked empathy.

In her world, there is only loss and profit. No goodwill, no love.

Inhumanly recognizing cold, mathematical logic as everything, she looks at everything in the world through calculating lens.

Return given profit with profit, loss with loss.

The girl was undoubtedly pure, yet undeniably abnormal—

Her favorite things are cooking, food, and being pampered.

Her specialty is mu*der.

—- This is the story of a slightly unhinged girl being surrounded by kind and loving people, and her journey to find happiness.
