On the Lunaris Festival, the palace banquet glittered with candlelight. It lasted until the Crown Prince rose and dismissed every consort of his for the sake of his first love, the woman he had never stopped idolizing. Everyone else accepted the gold coins from the prince and returned home for reunions. I had nowhere to go. I found a rope and hanged myself at the gate of the Withered Court. I had been reborn into this world and spent 21 years locked in the System's mission. It demanded that I court four designated male leads and earn absolute affection from at least one of them. I failed every route. The final path collapsed in my hands. The System offered one last mercy. If this body died, I could return home and reunite with my family. As my consciousness slipped away, I thought I heard someone scream my name, as if the world itself were breaking.

My childhood friend promised to marry me once we came of age — but at my wedding ceremony, he gave my wedding ring to my stepsister, Summer Hugh. At the time, it was Victor Lowell, the fearsome mafia heir, who saved me by publicly announcing he had loved me for years. In the five years we had been married, he would fulfill every wish I had, even those I mentioned offhand. I truly believed I was the center of his world. All that changed when I stumbled across a top-secret folder as I was cleaning his bookshelf. The very first page was a file on Summer, with three red words printed in bold, “Top protection priority.” It was followed by a mission report I knew too well. On the night of the mission, there had been an attempt on my life. My blood had almost run dry before I was saved. When I woke up at the hospital, I found out that I had lost a baby I did not know I had been carrying. I wept bitterly in Victor’s arms, but I did not tell him about the baby. I did not want him to worry about me more. Now, I finally found out — Summer had been attacked that night as well, and Victor’s orders had been: “Save Summer first.” My tears soaked into the paper, smudging his handwriting. “Alright,” I said softly but firmly into the silence. “If my marriage had been a lie all along, I’ll disappear from your life. Forever.”

At my wedding to my childhood friend, Mason Rivers, a stream of floating comments suddenly appeared in front of my eyes. [LMAO, supporting character still doesn’t know the groom is a stand-in! The real male lead, Mason Rivers, is at the hospital with the fragile, sweet female!] [It doesn’t matter who the groom is. He only agreed to the marriage to keep his company afloat. This story is about the childhood sweetheart losing to the girl who came later.] [In the end, the supporting character gets completely ruined by the male lead. I almost feel bad for her.] I hid the shock in my eyes and pretended not to know anything as I finished the ceremony. I didn’t want to be the stepping stone for their love, the disposable extra who dies a tragic death. If he didn’t want to marry me, then I’d turn this act into something real and marry someone else instead.

I woke up inside a novel, and not even as an important character. I became a pretty background extra in a smut novel. My brother, however, was the only normal person in the entire story. His character setting was the one man the soft, delicate heroine could never win over. He was the cold, unattainable Prince Charming she could never conquer. When the heroine cried and confessed her love, he was studying. When she offered him her whole heart and body, he was busy starting a company. When she spiraled into scandals and nightlife, he was already a billionaire, calm and untouchable. I thought he would live a quiet, ascetic life forever. Until one night, I walked in on him at midnight… holding a piece of clothing I recognized all too well, murmuring a name over and over, a name so familiar that my scalp tingled.

Sia wanted one night, just one daring, unforgettable night with Knight Smithfield, the boy she’s quietly loved from afar. What she didn’t expect… was to kiss his twin brother instead. A masked moment and a stolen kiss that felt too right to question until a photo exploded across campus, turning her secret into scandal. Now, Sia is forced to be in a fake relationship with Richard, the wrong twin… and the only one who knows the truth. As if that wasn't complicated enough, their parents just got married, forcing all three under one roof. Living with the Smithfield twins should’ve made things clear. Love one. Hate the other. Easy, right? Except nothing feels easy when Richard starts becoming something more than a mistake, and Knight suddenly starts acting like he wants her too. One kiss changed everything. Now Sia is caught between two brothers, two hearts… and one impossible choice. Was it just a twisted accident— Or was it fate playing her hand?
