Lin Changfeng was an utterly ordinary office worker.
While staying up all night to conquer every ending of a certain adults-only NTR game, he was deeply shaken to discover that no matter how hard the player tried, the cuckolded protagonist's sisters and mother would always be stolen away by the blond villain.
Our poor protagonist, a knight of the church held in high esteem, fell into a deep slump and drank himself senseless day after day.
The theocracy gradually declined, until it was eventually destroyed by the resurrected Demon King.
And all because he stood up for the poor protagonist, the goddess sent him to the other world where the game took place.
[What a classic setup...]
With a mission from the goddess, he would become the protagonist's close friend, offer him support when he was at his lowest, help him get back on his feet, stand together against the revived Demon King, and save the world!!!
[That's definitely how the story will go from here, right?]
But who could have guessed that one day, the protagonist would wake up as a beautiful, pure-hearted silver-haired girl!
"...?"
[W-well, never mind...]
The young man had become a young woman, which seemed to be a slight departure from the original plan...
But if he kept offering her support and reassurance, surely the poor girl would get back on her feet, right!?
[Probably... right?]
Holding to this strategy, as they spent day after day together, the shadows in the poor girl's eyes did indeed disappear.
But the way she looked at Lin Changfeng... seemed to hold a hint of... possessiveness?
"I once believed I would never find happiness again. I abandoned my ideals and grew more despondent with each passing day."
The silver-haired girl turned to look at him, unable to hide the love in her eyes.
"But now... it seems I have a reason to draw my sword again."
