The male protagonist of the book "The Rise of the Talisman Masters" always wore a mask with runes on his face. I recommend this novel to you. The plot is very interesting. I suggest you read it. I hope you like this fairy's recommendation. Muah ~😗
I recommend "The Playful Concubine Ghost Prince", an ancient romance novel. The male protagonist, Prince Jin, had a long centipede scar that made him ugly. From the beginning, his door was like a market, and now no one dared to come to him. He often wore a mask and was a cold-blooded and ruthless character who killed people like they were numb. However, when he met his cute little wife, he became a gentle and domineering man. [I hope you like my recommendation, Mwah~]
I recommend the following two novels to you. They are "After I Transformed into a Book, I Brought the Villain Big Boss to Clear My Name" and "The Cold King Dotes on His Daughter, Han Fei". The first novel told the story of the female protagonist transmigrating into the novel world and becoming the daughter of the male protagonist, who was a villain with disabled legs. She used her intelligence to clear the male protagonist's name. In the second novel, the female protagonist was the useless Sixth Miss, and the male protagonist was a cold prince. His face was destroyed and he wore a mask. There was an unusual love story between the two of them. I hope you like my recommendation. Muah ~
This novel was called "The First Seat of Love Rejection". The male protagonist got along cruelly with the female protagonist under the mask until the female protagonist couldn't bear to leave him. I hope you like this fairy's recommendation. Muah ~😗
This novel was called " The Alluring Medical Concubine ". The male protagonist, the Third Duke of the War God, had his face burned in a fire and had been wearing a mask ever since.
One possible reason could be for disguise. Maybe he is on a secret mission and doesn't want to be recognized easily. In the Naruto world, there are many dangerous foes, and wearing a face mask can help him blend in or hide his identity from those who might be targeting him.
In " Ugly Woman Bewitching the World: Disdain to Be a Concubine," the female lead always wore a mask and painted her face very ugly.
"Demon Concubine Alluring: Your Highness, don't be reckless!" This was an ancient romance novel. The male protagonist was a deposed king whose face was completely ruined. He always wore a mask to show others. The female protagonist was the most shameless and ugly woman in the entire Northern Mountain Country. However, she later turned into a world-toppling beauty who was skilled in both medicine and poison. Their love was full of thrills and changes. It was not until the mask was broken that she discovered the true face of the male lead. I hope you like my recommendation. Muah ~
The male protagonist wore a mask and was called "Sword Hidden in the Void." He was actually a peerless genius. The genre of the novel was fantasy romance-Oriental fantasy, which met the requirements of the question. I hope you like my recommendation. Muah ~
It could be for a more personal reason. Maybe he's going through some internal struggle or self - doubt, and wearing a mask is a way for him to create a new persona, a stronger and more confident version of himself. It's like a shield that allows him to face challenges he might not be able to as the regular Naruto.
