Until he chose another woman and signed away his marriage without regret. Mia Hale vanished the night their divorce was finalized. The world said she died. Allen believed it—and moved on. But Mia lived. Reborn as Iris Morris, the sole heiress of a legendary billionaire dynasty, she returns years later with unimaginable power… and two twin boys Allen never knew existed. Boys with their eyes. His blood. His past. As Iris quietly dismantles Allen’s empire, he’s forced to face the truth: the woman he destroyed is the one holding his future—and the sons he never deserved. Now regret is no longer a feeling. It’s a reckoning. Mia must decide if the man who broke her heart deserves a place in her sons’ lives… or if some betrayals come with no second chances. Because some loves are realized too late— and some regrets last forever.

After the SAT, I come across a post online. Someone posts, "If you could make a choice all over again, which major would you choose this time?" The comments are filled with people wishing they had chosen a different major. They all have their own regrets. One response stands out from the rest. "I would choose literature. That way, he and I wouldn't have missed out on the four years we should have spent together because of that unwanted baggage." I chuckle and am about to scroll past when I suddenly notice the profile picture and username. They are identical to those of my childhood sweetheart, Winter Andersen. I click into the profile. Everything matches her current account exactly, except that the age is ten years older. My heart sinks to my stomach. This has to be her ten years in the future. No wonder I am the only one celebrating when we are admitted to the same major. No wonder she zones out for so long after seeing my best friend, Simon Brown, receive his acceptance letter from the literature department. It turns out I am the unwanted baggage responsible for so many of her regrets and disappointments. Since that is the case, I quietly press "Accept" on the admission offer written entirely in a foreign language. I shall end this mistake ten years ahead of schedule.

For years, I endured his cruelty in silence… until the day my sister returned… perfectly healed, determined to reclaim him. So I signed the divorce papers and walked away. What he didn’t know? I was carrying his child. Years later, I’m no longer the broken girl he once despised. I’ve built an empire from nothing, and now, I stand as his equal… his rival. But when the truth finally comes out… when he realizes I was the one who saved him all along… will his regret be enough? Or is it already too late to win back the woman he destroyed?
