Kuroitsuki

Xion Aijawa thought his life was finally coming together. That is, until he tried saving a cat stuck in a tree, fell into a pit, and... died

In his disoriented sate of "Freshly dead" the silly Xion accepted a strange request and ended up transmigrating into the world full of dungeons and Mana. 

He became illegitimate child of Marquis family hated by his three siblings.

According to the memory of the original owner of the body, Xion only had a month to live.

So, taking the cover of the banquet, Xion ran away. Aided by a mysterious Mall System, he makes his way to the distant borderlands, hoping to put his past behind him. 

But fate has other plans-. Xion ends up saving Darius Rael Darkhelm, the feared Archduke of the North, notorious for his ruthless and deranged nature. 

The silly Xion tried to run away but...

 Xion's heart thumped loudly as Darius effortlessly pinned his wrists using only one hand.

"I've heard you tried to run away."

Darius gently caressed Xion's pale cheek, "That must be a lie... After all, I've given you things even the royal family can't have. Isn't that right, my dear healer?" 

Xion gulped when Darius's thumb brushed his lower lip as a chilling smirk remained on his handsome face.

 "I-I think I should leave, Your Grace. I've overstayed my welcome..."

The room grew cold, and struggling Xion shivered.

 Darius's green eyes dimmed before lighting up with a dangerous glint. 

Xion felt a pit growing in his stomach when he saw the deranged archduke smile. Darius never smiled. And whenever he did, it only meant trouble.

"You're right," Darius said calmly. "So, let's get married."

Xion "...!!!!"

[BL] Accidentally Becoming the Healer of the Deranged Archduke

Xion ignored the sly smile on Rael's face as his thought drifted to another issue he had been putting past him. Nikolai's face reminded him of the lady who kidnapped him.

"You know," Xion spoke thoughtfully, "that woman who kidnapped me looked a lot like Nikolai. She had golden hair. Her eyes were hidden beneath a veil, but I think… they were somewhat yellowish."

There was one royal princess, and she was Talia, his cousin. Of course, that was only true if one ignored His Majesty's rather lose control over his lower body.

That old man had more illegitimate children than legitimate ones.

And if Xion's guess was correct… this woman might just be one of them.

"She could be, or she could just as easily not be Nikolai's cousin," Darius mused, his gaze drifting toward the wooden chest tossed carelessly in the corner of the carriage. "The royal family is far messier than you can imagine."
