I Created A Harem of Waifus and Now I Have To Win Their Hearts to Save the Multiverse!: The Harem Heart

He created them. Now he has to earn them. As an author, he poured pieces of his heart into every character he ever wrote — literally. What he didn't know is that those pieces were fragments of a Worldshaper's soul, ancient power capable of collapsing possibility into reality. His characters are real. Eight women across multiple worlds, each carrying a shard of his heart like a seed. And because his heart is fractured, so is the multiverse. The cracks are growing. Demons are pouring through. And a being called the Voice Between Worlds has made one thing painfully clear: the only way to seal the fractures is for each woman to willingly return her Heartkey — not taken, not stolen, but given freely, born of genuine connection. So he goes to them. The field hockey captain with green hair and a laugh that could restart the world. The goblin who washes gold coins in waterfalls. The cybernetic heroine who dispatches criminals with the calm of someone who scheduled it. A cat-girl. A baker. A warrior. A mother. And somewhere behind them all, a darkness that knows far more about him than it should. He's an author who fell in love with his own stories. Now he has to earn them back — before reality runs out of time.
