Oopss... I Married My Boss - Chapter 25: Sealed With a Lie

Protagonist travels between different anime worlds to right wrongs and uncover his reason for being along the way.

Ukei Kaito fought a desperate struggle in order to fulfill his role as a summoned hero. He defeated the Demon Lord and saved the very world, only to meet an end filled but with betrayal. The companions that he’d trusted throughout his journey betrayed him and killed him by sticking a blade through his chest.

Michael Alastair never mattered. In a world where strength was everything, he was nothing—just another powerless kid, easy to break and easier to forget. When his tormentors finally took things too far, his story should have ended in that alley, bleeding and alone.But fate had other plans.In the void between life and death, a voice spoke. Cold. Sharp. Amused. [NEW TALENT UNLOCKED: WRITER’S LEGACY]. A system unlike any other—sarcastic, relentless, and strangely invested—offered Michael a power beyond reason and a purpose he never imagined. Now, armed with an SSS-rank ability and a mission to rise, he’s back. And this time, he won’t just survive—he’ll rewrite the rules.

This novel is also known as Only I Level Up

10 years ago, after “the Gate” that connected the real world with the monster world opened, some of the ordinary, everyday people received the power to hunt monsters within the Gate. They are known as “Hunters”.

However, not all Hunters are powerful. My name is Sung Jin-Woo, an E-rank Hunter. I’m someone who has to risk his life in the lowliest of catacombs, the “World’s Weakest”.

Having no skills whatsoever to display, I barely earned the required money by fighting in low-leveled catacombs… at least until I found a hidden catacomb with the hardest difficulty within the D-rank catacombs!

In the end, as I was accepting death, I suddenly received a strange power, a quest log that only I could see, a secret to leveling up that only I know about! If I trained in accordance with my quests and hunted monsters, my level would rise.

Changing from the weakest Hunter to the strongest S-rank Hunter!
