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 stared at Xion as if the healer had just asked whether the sky was blue. Was it not already obvious?

"I don't have one," Darius answered flatly.

Xion's eyes widened slightly, then narrowed as he studied the boy. He was pondering if Rael was speaking the truth or just bluffing him.

"Really? I thought it was normal for someone in your position to be engaged for political reasons."

"It is," Darius admitted, "but I never agreed to such arrangements."

Xion leaned back against a pillow that hadn't been there before, "So, no secret lover? No long-lost childhood sweetheart waiting for you in some distant castle?"

Darius shot him a dull look. "No."

Xion chuckled. "Well, that's a shame. I was expecting something."

The carriage swayed gently as they continued down the new road.

Xion was not entirely wrong. However, Darius did not feel the need to tell the entire truth.
