Infinite Harem System: I Grow Stronger From Every Female Lead

PLEASE READ THE SYNOPSIS FIRST!! Main Plot Points → Harem, Romance, Fantasy, Slice of Life, Academy, Action, with a touch of Mystery. 『 Disclaimer: This work is heavily inspired by the Webtoon character Na Kang Lim (my favorite harem story) and Magic Academy’s Genius Blinker 』 『 Certain character dynamics, themes, or plot elements may reflect homage to these sources 』 ↓ Synopsis → Beom-seok was a virgin gamer with a simple dream: to get his first kiss. After years of loneliness, he finally lands a girlfriend, a shy, nerdy otaku girl. The day they planned to share their first kiss was also the day he completed their favorite RPG. But fate had other plans for him. And smashes into him. Literally. And just like that, he died. Just inches away from her lips. The next time he opened his eyes, he was no longer on Earth—but inside the world of The Magic Academy's Genius Scholars, as his avatar: Arthur Arcain, a character so fragile and pitiful he was only added to the game for fan service. Ridiculed by players. Unable to store unrefined mana or force. And destined to die no matter what route you played. But Beom-seok knew the truth: Arthur wasn’t just some extra. He was the sole male heir of a powerful, all-female demonic dragon clan, and he possessed the greatest magical potential in the game—if only his body could handle unrefined mana and force. Luckily for Beom-seok, a mysterious system activates, changing everything. A system that links his survival to the game's female leads. A system that rewards him for completing their scenarios… and growing their affection bonds. The more they fall for him, the more refined mana, force and stats he gains, making his power and talent close to none. But there’s a catch. If he fails a scenario? The world ends. And he dies. ----- And No! Anna isn't his wife god damnit.
