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

Xion slowly lifted the duvet over his messy head. He peeked around, and only when he saw no one in the room did he breathe a little easier.

Only after relaxing did his focus shift to his surroundings. It was an unfamiliar room.

His surroundings were exotic, far too lavish to be an inn, yet too artistic to be associated with Darius. The warm scent of paint and fresh flowers filled the air, mingling with the faint traces of something sweet, maybe wine?

Xion could not tell. He hesitated before sitting up. There was sharp pain near his shoulder, exactly where Klein had dragged his knife. He rolled his shoulder lightly to ease the ache.

Dragging his shirt up to see his chest, he saw it. A scar the size of a hand directly above his heart.

The System Can Speak?!!!
