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

Darius did not need to look in the mirror to know that a murderous hunger was slithering its way into his eyes. The bloodlust was humming in his veins. So sweetly, so intensely.

His hands carefully wrapped around the small figure. Even as he lifted Xion effortlessly into his embrace, the boy, who should have stiffened, should have widened those innocent eyes in fear or disbelief, remained muted.

A muscle in his jaw ticked. He exhaled slowly, forcing restraint over the dark impulse curling in his chest.

"B-Brother said not to touch him. A-and not to come close."

Noxian stood rooted in place, his tiny fists clenched at his sides. His dark eyes shimmered with unconcealed worry.

"I... I kept calling him. I shook him, but he wouldn't wake up," Noxian almost bit his tongue as he hastily told what little whispers he had heard.
