Sin System: Demonic Harem After Reincarnation - Chapter 1

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.

“Ah…” She is so tickled that she is defenseless against his attacks. “You can choose to marry me or to die!” By then you will become the first person in history to die from tickling. “If you dare to reject me, I will make sure to ravish you until you yield to me.”

“Block him.”“He's technically still my boss.”“Then block him with dignity.”The call ended again.And then started again.I let out a sound somewhere between a growl and a sob, then finally answered with the enthusiasm of a snail crawling through salt.“Yes, Mr. Walton?”“Have you changed your mind yet?”I collapsed onto the towel and gazed at the sky as though it might consume me entirely if I pleaded sweetly enough.“Do you ever take a break?” I asked, shielding my eyes with one hand.“You're avoiding the question.”“Because it's a dumb question.”He exhaled, the sound sharp and irritated even over phone. “It's not a dumb question. It's a business offer.”“It's a weird offer-one that I already said no to.”There was a brief pause, and I could practically hear him clenching his jaw through the speaker.“You are acting unreasonably.”“ Unreasonable?” I sat up. “I'm not the one drafting fake girlfriend contracts like it's a normal Tuesday.”“Isabella-”“Certainly not, Mr. Walton.” I mimicked his tone perfectly. “I told you I'm not doing it. You need to find someone else to play pretend with.”SYNOPSISIsabella Miller thought saying no to her boss’s fake dating offer was the end of the story.But Adrien Walton doesn’t take no—especially not when he’s convinced she’s a gold digger.Suddenly, her student loans are piling up, her father’s vet clinic is on the brink of eviction and her brother is about to be kicked out of college.
