A Mafia’s Vow

"Five years ago, you threw me away for power... Five years later, you return as the reaper who saved my child... The child you never knew existed."
‘Mirin,’ an omega who fled the devastating heartbreak of her former lover, has spent the past five years raising her four-year-old daughter, ‘Mia,’ entirely on her own. She thought she had finally escaped that pitch-black world until the day her precious child was violently kidnapped by a mafia syndicate right before her eyes!
And the person who steps out of the shadows to save the little girl is none other than ‘Rena Vesper,’ the alpha heir to the most formidable mafia empire in the country... the heartless reaper who left an agonizing, permanent scar on Mirin’s soul.
When the existence of the hidden heir is exposed, enemies from every direction close in to hunt the little girl down. The absolute only way to ensure her daughter's survival is for Mirin to step willingly into a gilded cage forced into a sham marriage with the very alpha she despises in order to consolidate power and secure their protection.
"You saved my daughter... but you will never, ever have my heart again."
What will Rena do... when a mere piece of paper cannot bind the heart of the fierce omega she lost? And what will happen when the devastating ‘secret’ the truth Rena bought with her own blood and tears to protect Mirin five years ago is finally brought to light?
