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

Soon, the freshly cooked food was delivered to his door, and the one who came with the servants was none other than Noxian.

The boy didn't hesitate. He jumped onto the bed without a second thought. "Brother, how are you feeling? Are you fine now?"

Xion couldn't help but feel like an irresponsible adult for making his little brother worry.

Without a word, he lifted the purple haired boy and settled him onto his lap.

The boy blinked in surprise but quickly found himself wrapped in a warm embrace. Though still a bit confused and worried, he instinctively hugged his brother back.

"I am sorry for making you worry."

"I was really scared when I saw you like that," The boy murmured in a low voice. He clearly did not want to recall the bloody picture of Xion looking so lifeless.

Xion easily diverted the topic to other things while patting the small back until the tense body relaxed in his arms.

Not much. Just 500,000 Merit points.
