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

The day had been so enjoyable that when Xion returned to their temporary residence, he barely had time to process the sudden invitation to a night party.

To understand, time needs to rewind a little.

Allen had bought a brooch, some writing quills, and ink. All this while, Xion had done nothing but enjoy the view and indulge in playing dress-up with Noxian at every clothing store they passed.

Judging by Noxian's glowing face, the day had clearly been enjoyable for all of them.

"Thank you, Brother! You're the best!"

Noxian's grin was so infectious that Xion couldn't help but ruffle his hair.

"Go on, try them on. If there's anything you don't like, we'll get a new one."

"As if he'd ever dislike them," Allen muttered under his breath, eyeing Noxian as he bounced around excitedly in his new shoes.
