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 dragged Allen away before making his way toward the hidden corridor, completely unaware of the angry glare settled on his back.

"Are you okay?" Xion asked the silent Allen.

Allen was more than just okay. He was giddy, and it was evident in the way his eyes shone. "Yes. Thank you."

Xion waved his hand dismissively. "Forget it. Don't let them bully you like this."

Allen nodded along. It wasn't that he did not want to, he just couldn't. Perhaps it was his instinct trained by his childhood, but his body felt frozen.

That was until a small frame protected him. It really was a blessing to know Xion.

When Xion's anger calmed down, he sighed, "Let's go back, or His Highness might get angry."

The people who had been stretching their ears to listen to their conversation were already laughing and talking with others. It really was like a stage where the actors played their roles to perfection.
