Will his (terrible/excellent) mentality help him make a fresh start? Will he get through misfortunes and hardships of the new world?

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!

I became the fiancé of the tyrant male lead, a character who becomes a villainess because she was obsessed with the beautiful tyrant.

Of course, in the end, she was killed by the tyrant.

Still, this all happened before the original story began.

After diligently performing a dozen or so actions that would cause me to be dumped by him, I succeeded in becoming a sound friend of the tyrant, who turned out better than I had thought.

“How was it?” asked the female lead, who he saw for the first time.

“Hmm?”

“I meant your meeting with Miss Diel (female lead), Your Majesty.”

He tilted his head slightly. Hey, don’t pretend you aren’t interested.

It is said that he fell in love at first sight, but I saw it all.

Hehe. I chuckled and poked his arm with my finger.

“You know what? Please let me know if you have someone you like.”

“Why? So you can kill her?”

Heh, do you think I’m like you?

I smiled sincerely and answered him. “Well, I’ll break off our engagement at the right time.”

“Miss.”

The smile on his face disappeared in an instant.

I somehow became speechless after my gaze met his glaring eyes.

He stared at me and laughed quietly in a slightly husky voice. In a subdued voice, he then said, “Don’t make a joke like that.”

His hand stealthily and gently brushed off the strand of hair on my cheek.
