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

Every prisoner inside had long since resigned themselves to their hellish fate.

The peacekeepers rarely spoke to them. Their only form of interaction was delivering beatings or tossing in a fresh unfortunate soul.

A young man with disheveled dark hair sat cross-legged on the bloodstained floor. The prisoners had assumed that the color was dark purple as they could not properly see it due to the dim light.

The young man with a tender, innocent face looked completely unbothered by the horror surrounding him.

With curious equally dark eyes, he leaned forward. He picked up a small twig from the floor and traced it along the smooth surface of a chained skeleton's ribs.

"Look at this, brother." Xion tapped the bones lightly, "See how the ribcage curves inward? This suggests prolonged malnourishment. The sternum is slightly concave... probably due to excessive beatings in the past. And see these marks?"

Xion Is A Lunatic?
