MTL - The Roots of Manga - Chapter 74 ask for

In his past life, Ethan Steele was an ordinary man living in a modern world—working a dead-end job, struggling through the monotony of daily life, and haunted by regrets of missed opportunities.At the age of 23, his life came to a sudden, unexpected end in a car accident. As his consciousness faded into darkness, he was sure it was over.But fate had other plans. In the divine realm, the God of Fate watched over the balance of life and death.Ethan's untimely death was a mistake, an anomaly that diverged from the preordained path of his destiny. It wasn't yet his time to die, and so, the god decided to give him another chance.“You were meant for greater things, Ethan Steele,” the god's voice boomed. “To correct this error, I will reincarnate you in another world—one filled with magic, swords, kingdoms, and adventure. You shall be reborn, but you will not remember your past until the appointed time. There is, however, a... complication.”By divine error, the god accidentally bestowed Ethan with the Harem God System without having any idea about it.This system is a powerful, reality-bending system that would allow him to charm and seduce influential women to build his harem, growing in strength and power with each conquest.“Your memories of Earth will return on your seventh birthday. I hope you enjoy your life here in this world”And with that, Ethan's soul was transported to a new world.

In her past life, Chen Wei’er was too blind to recognize people for who they were. She caused the destruction of her own family for the sake of a scum, and hurt the people who truly loved her. Fate gave her another chance to start over. In this life, she became decisive and worked hard in her career. She became a proud dance queen who managed to destroy the third-wheel who schemed against her, take revenge on the scum, and avenge all past grievances. She became a sweet wife who was coquettish and flattering, boldly seducing her aloof husband, He Xun.

His difficult wife suddenly became sweet and gentle. He Xun finally couldn’t resist holding her tight and whispered into her ear, “What do you want? I’ll give you everything. My life is yours too, so stop teasing me…”

One night, Chen Wei’er had a dream. She dreams of her past life, and the world after her death. He Xun was sitting in the hospital’s corridor, hugging her bloodied corpse as he went insane. “Had I known that in exchange of letting you go, you would die instead of being happy, I would never have let you go…” Then, He Xun killed all of her enemies and built a small wooden house in front of her grave. He never took another wife but became her grave-keeper. To think he loved her so much. Then, she learned that fate only gave her another chance to start over because this man, who had loved her for two lifetimes, had begged in front of her grave day and night for another chance in exchange for a lifetime of loneliness…

Instead of causing chaos with my knowledge of the original work, I assisted the protagonist.

I successfully completed the story and now planned to retire and live peacefully.

However, it seems the protagonist still needs my help.

An academy professor? That’s nothing much.

But why is the state of the academy so strange?”
