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.

I think this novel was pretty decent read, though it did feel a bit underwhelming at the end but it was still an enjoyable read!! Her father is very doting and I find his behavior funny sometimes because of the way he boasts about his daughter and is like the typical doting dads in novel stories. There is also a slow burn romance and had a fair amount of cute scenes between the FML and ML. One thing that bothered me was that FML and ML became step siblings... more>> later on in the novel. She did eventually leave the family register but for the small bit of time when they were step siblings made me uncomfortable. Overall, read this story if your looking for something unique. Mind you, I wouldn't say this is a masterpiece but I do like it enough to finish it all the way till the end. <<less
