MTL - Non-famous Actor - ~ One thousand two hundred and eight, the incident happened suddenly

Xue Xi is forced to fall in love at first sight with this dangerous man on their first meeting. With death being the only other option, she makes the first move:

“Failed writer. Failed hunter. Failed at life.”Aiden Jus had heard it all before. At twenty-eight, he was a walking reminder of what happened when you failed your mana awakening and spent thirteen years chasing a dream that would never come true. No powers. No future. Just a cramped flat in the UK and a lifetime of rejection letters from publishers who never bothered to read past the first page.But the day Aiden decided to give up on writing—the day he was ready to finally accept a soul-crushing desk job at an editing firm—everything changed.*[You have been chosen by Nabu, God of Literacy and Scribes]**[Skill Acquired: Narrative Embodiment (Divine-Rank)]*The ancient Mesopotamian deity offered Aiden something unprecedented: the power to physically enter any story he writes and gain real abilities from the fictional worlds he creates.*[You have mastered Celestial Blade Art - Skill permanently acquired]**[You have learned Tier-9 Spell: Void Severance - Spell permanently acquired]*Every sword technique mastered, every spell learned, every power gained inside his stories becomes permanently his in the real world. But so does every death trap, overpowered villain, and narrative cruelty he carelessly wrote in moments of frustration.Suddenly, Aiden isn't just a failed writer anymore. While other awakened humans rely on mana cores and dungeon raids, Aiden's strength comes from the worlds born from his imagination—a power that operates outside the traditional hunter system entirely.As rival gods compete for powerful human contractors and ancient ruins promise unimaginable treasures, Aiden must survive the deadly fictional universes he created while building his reputation in a society that once dismissed him as worthless.**From the typewriter to the battlefield, Aiden Jus will prove that the pen truly is mightier than the sword—as long as you're willing to live through every word you write.**
