My handsome, overpowered dad, who only ever cared about me, ate something strange and turned into the Demon King. He used to be the sweetest, most doting father, but now he’s the final boss?! Because of this, my dad is fated to be killed by the male lead, and I’m destined to die lonely while mourning him. At that moment, I returned to the past and realized that this world is actually a game! I couldn’t prevent my dad’s descent into darkness, but no matter what, I must turn him back into his original self. If I succeed, I can get my loving dad back, right? For now, I need to get close to the male lead, who’s destined to kill my father…! So, I became a Holy Knight and even managed to be adopted as the ward of the Pluto Ducal House—the male lead’s family. …The problem is, I’ve become way too strong. As long as I get along with the male lead, my dad might avoid being labeled as the Demon King. “But that’s strange.” “…What is?” “Your lips… they’re heart-shaped.” “W-what? Don’t look at my lips!” At that, the male lead tried to avoid my hand and ended up rolling under the bed. “Ahhh!” “…?” He’s supposed to be the strongest person who’ll one day kill my dad, but for now, the male lead is just too cute.

Chen Qizhao was reborn and returned to the age of 18 when he was still the wicked little overlord of the Chen family.

At this time, his brother hadn’t experienced a car accident while his parents were in good health and weren’t seriously ill. The Chen family was still the prosperous Chen family and everyone thought he was a good-for-nothing who was useless and easily taken advantage of.

“He only knows how to quarrel with his older brother every day. He is arrogant and willful!”

“He looks good, but unfortunately, he is an idiot.”

“Isn’t he a useless person? Just serve him well.”

“It is a pity about that child of the Chen family.”

There were the group of scoundrel friends who were full of thoughts, the rats eyeing him covetously and the old, cunning people who were secretly scheming.

Chen Qizhao put on a mask of arrogance again. ‘Do you like acting so much? Why don’t we act together?’

It wasn’t until later that everyone discovered that at the end of the play, they would either go bankrupt or be imprisoned.

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 dungeons, the “World’s Weakest”. Having no skills whatsoever to display, I barely earned the required money by fighting in low-leveled dungeons… at least until I found a hidden dungeon with the hardest difficulty within the D-rank dungeons! 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!
