It's Actually Not Easy Wanting to be a Supporting Male Lead - Chapter 1.7

An unknown parcel arrives to Yoshio, a 30-years old NEET. The content is a game disk titled “The Village of Fate.” A beautiful CG game with real-life images gets started.

He became a teacher at the best magic academy in the empire.
….For being mistaken for someone else.

Arthur got randomly transported to another world. Some people would find that terrifying, but not for him, who was tired of his old life; it was an opportunity.

And, after having bad luck all his life, the tide changed.

It was a world of magic where wizards fought side-by-side with their familiars. Arthur got summoned to be one of these so-called familiars.

He was furious. The thought of becoming a pet was not something he liked. Well, that changed when he saw who his master was.

A hot-woman. And, to make everything better, Arthur was inside the Frostpeak Magic Academy, which only had women students.

“This is heaven. All familiars are beasts, but I'm different. I'm a good-looking man inside a place filled with hot girls.”

When he thought his luck could not get better, he unlocked a system that helped him with everything. Of course, he used the system for a greater good, like getting girls.

Within the red tent, under the passionate eyes of the man on top, she was forced to make love and three thousand black strands turned to white.

Outside the red tent, her husband laughed and drank with the beauties by his side as they watched…

When the red was torn, pieces of it were carried away by the wind. As she stepped out with difficult steps, the silver hair danced in the wind. Exactly whose heart was the one that was hurt in the end?

“How…how could it be you?” A voice filled with disbelief, he who always believed himself to be cold and unfeeling, fell into the pits of hell, filled with pain and regret for eternity.

For this imperial power, there are countless hidden plots. She hid her capabilities and bided her time, only desiring for a safe haven. In the end, her wish did not come true, and she fell into the hands of someone else as a chess piece.

The tale of a time-traveling woman who gets forced to the point of no return, turning her black hair into white. Should she bow to her fate and submit? Or should she fight back and glow brilliantly?
