Everyone in Makati calls him Tito Marcus — the billionaire who built hospitals, funded scholarships, and never let a single relative go hungry. For twenty years, he's kept one secret even from himself: he's in love with the one woman he can never have.
Ate Grace Bautista teaches other women how to save their marriages. She has a parish full of devoted followers, a fifteen-year marriage everyone envies, and a husband who hasn't really looked at her in years.
One typhoon-soaked night at Marcus's Tagaytay estate changes everything between them. By morning, they've made a vow to bury it forever.
But someone already knows.
"I know what happened that night."
The messages start small — a photo, a whispered threat — and Grace assumes it's about money, the way it always is when the rich are involved. Marcus is ready to pay whatever it costs to make it disappear.
Then the blackmailer sends one more message, and everything they thought they understood about that night collapses:
"I don't want your money. I want you to know who you really are to each other — and why your parents made sure you'd never find out."
Grace and Marcus aren't just cousins protecting a shameful secret. The secret is protecting a truth about their own bloodline — one buried twenty years ago by the two people they trusted most, and now surfacing to destroy every single thing they've spent their lives building.
The person hunting them isn't a stranger.
They're already inside the family.
Borrowed Sin — a romance built on a lie no one dared to tell, and a revenge two decades in the making.
