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

"I lived with my teacher before I was taken to the Marquis' estate," Xion nervously flicked his gaze to Rael's inquisitive eyes. "Even if I don't have money, I still have a few medicines with me. My teacher wanted me to sell them if I ever needed to."

Xion forcefully plastered a small smile on his face, hoping it would put some sincerity into his words. Inside, though, he was mentally giving himself a thumbs up.

He had managed to come up with a story that not only explained why he had special items but also subtly hinted at the reasons behind his decision to run away.

Rael's grip on his chin loosened. Without another word, the boy leaned back into his pillow.

This much should be fine, Xion pondered. By the looks of it, Rael obviously believed him.

Darius did believe him, however, his query was never what Xion had assumed it to be.

Xion belongs to me now, does he not?
