Now trapped in a fake engagement neither of them planned, Amara and Adrian are forced to keep up the act in front of suspicious friends, nosy family members, and a growing number of people who are far too invested in their relationship. The problem? The more convincing they become, the harder it is to remember what’s fake and what isn’t.

What would you do when you discover he was the same guy left hanging at the altar earlier that day? You regret everything, of course. What would you do when you start seeing that same guy everywhere you go? You fall in love, of course.

After transmigrating into a novel, I realized the heroine and I had the exact same name. Naturally, I thought I had transmigrated into the female lead. So I marched straight to the man who was still a broke nobody at the time, threw all caution to the wind, and pounced on him like I had plot armor protecting me. He even glared at me with red eyes and told me he hated me. I honestly thought he was just into the whole push-and-pull thing. Everything shattered when the real heroine showed up and I finally understood one thing. He actually hated me. Heartbroken, I packed my bags and got ready to disappear. The next second, he pinned me against the wall. "Where are you going? Already bored of me, sweetheart?"

She lost her memory, he lost his heart, but was she ever more than just a replacement? Andre had rescued Lisa after an accident, but unfortunately, she lost her memory. Andre then asked Lisa to become his contract lover. Over a period of time, their relationship transformed from hidden to open and from fake to something real. Andre even proposed to her. However, on the very day of the proposal, Andre encountered a woman who had been missing for three years (Diane), who turned out to be Andre’s first love, and Andre never gave up on finding her. Diane appeared mentally confused and physically weak. Andre immediately abandoned his newly engaged fiancée to care for Diane. It was at this point that Lisa discovered she looked remarkably similar to Diane. She realized that throughout these years, she had been nothing more than a substitute for Diane, with Andre even styling her clothing to match Diane’s preferences. After Diane’s return, Andre’s attitude towards Lisa changed dramatically. Diane got more of his attention after telling Andre that she had been kidnapped. Lisa was neglected by Andre and simultaneously provoked by Diane, with Andre believing Lisa was jealous of Diane. Utterly disappointed, Lisa decided to leave Andre. When Andre figures out, he actually loves Lisa and that Diane had been responsible for her accident, he goes in search of his love. Diane is psychotic, and her disappearance was staged; she faked her kidnapping to figure out if Andre would remain loyal. Now, with betrayal burning on all sides, and secrets threatening to explode, Lisa must reclaim her identity, her past… and her revenge. Because this time, she won’t just survive, she’ll make them all pay.
