Your Girlfriend Calls Me Daddy

[!]: NOVEL START: Your Girlfriend Calls Me Daddy[!]: Genre: [Isekai Transmigration] x [Academy Harem] x [Power Theft][!]: Objective: Steal the Heroines. Copy the Powers. Rewrite the Ending.===Rome D'Angelo woke up in the body of a webnovel's disposable villain, the arrogant playboy rival designed to lose, suffer, and fade into irrelevance by chapter fifty.The system gave him two ultimatums and zero sympathy:Complete the “Harem Lord” ending in 700 days, or die.Graduate top-five at Coastline Hero Academy, or lose everything.His advantages? A face that opens doors, a fortune that closes mouths, and an SS-Rank ability the world thinks doesn't exist.[ ESSENCE DRAIN ] — Power theft through intimate contact. The deeper the bond, the stronger the copy.Registered as a “Passive Null,” Rome is invisible to the system that governs this world. Which means he can break every rule, as long as nobody sees his eyes glow.The original story was a pure-love romance about an earnest hero winning seven hearts through effort and sincerity.Rome read three chapters, skimmed to the ending, and forgot half the cast.Now he has to steal those seven heroines from a protagonist he barely remembers, using meta-knowledge full of holes and an ability that turns every relationship into a transaction.His first target? Marilyn Cross: a devil girl with spatial powers, a merchant's mind, and a smile that promises trouble.The complications? Cheon Hae-Won can see his stolen abilities. Noel Stark has a childhood grudge he doesn't remember. And the original hero, Nolan Traore, is exactly as pure-hearted as advertised.Every kiss is a power-up. Every secret is a liability. Every heroine he claims pushes him closer to godhood and further from the man he used to be.Rome didn't choose this story. But he's going to finish it his way.
