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

With his magic robe stained from the bloodshed of the previous night, Xion had no choice but to settle for a simpler garment.

He wondered if he should buy a new grey robe for his use. But he did not want to waste his merit points for now.

Draped in a plain blue robe that curiously mirrored the hue of his eyes, he made his way toward the door.

Xion looked at the shiny doorknob in his hand and suddenly remembered that, just a day ago, he had patted Rael's head.

How afraid he had been to even step out of the room? However, forget punishment, Rael did not even scold him.

His gaze drifted to the boy, still fast asleep on the bed. His cheek was smushed against the pillow, his soft, pouty lips slightly parted. All of it made him look so innocent, so adorable.

The sweet angel's peacefully snoring sight made Xion almost coo at him.
