Genius Neurosurgeon Lǐ Xīnyuàn died while being held at the gunpoint to perform a surgery on a terrorist leader.When he opened his eyes, he had transmigrated into a world similar to a Webnovel he'd been forced to read by a colleague.Now you'd think Lǐ Xīnyuàn had transmigrated into that Webnovel. But did he?No! Instead he'd been transmigrated into that webnovel's spin-off/“what-if” version of the story with nothing but the superficial knowledge of the plot thanks to reading the main novel.Now tasked with the mission of avoiding plotholes, unnecessary dog-blood, death and following the storyline to ensure the male lead's ascension to the throne of Supreme Emperor, he didn't know whether to laugh or cry.And why did no one tell him that his character had to be married into the Male Lead's harem??What about the Female Lead?Later:Lǐ Xīnyuàn: Why doesn't Your Highness spend the night with concubine Yang?ML: Don't want to.Lǐ Xīnyuàn: ... Why?ML: Are you pushing me away?Lǐ Xīnyuàn: QAQ

Being given a chance and reincarnated is nice and all, yet why do I have to become that male friend who just watches the protagonist flirting with his harem?---World: Kaguya-sama: Love Is War - Hyouka ----

This is the stories of two different people from two different worlds (literally)

She was raised in love, while he was raised in hate

Her birth was celebrated, while he was despised

She was protected, while he was abused everyday.

She is gentle, warm and kind, while he is cold, cruel and vicious

But with the twist of fate, their world collided. They will learn from each other.

He will teach her to be hopeful and live for herself, while she will teach him the joys of Friendship and Love

Together they will learn to understand each other, accept each other and love each other, and soon their love will change the fate of the world

Princess: Can you stop staring at me while I'm sleeping?

The Lord: I can't…

The Princess: Are you gonna stare at me the whole night?

The Lord: Yes!

The Princess: Can you at least act like a normal man who will take advantage of a maiden while in her room.

The Lord: …this Lord would oblige

The Princess: WAIT… This princess is kidding, just kidding, wait…!
