Why is my husband a mastermind with schemes behind

Of all things, I was transmigrated into the body of a stepmother who lost her husband just a month after marriage, abused the heroine, and was subsequently killed by the mastermind, Duke Lakan. The only saving grace was that I hadn’t accumulated any bad karma yet! I vowed to quickly take the abused heroine and leave this filthy household! However… “You’re a beggar with no house or connections.” Under Imperial law, there is only one way to take an adopted daughter out: remarry a man of higher status than myself. Just then, a handsome Marquis begins to seduce(?) me. “I am confident I can hand over 32 bank accounts containing my entire fortune and the deeds to about five houses to Asha, so this is nothing.” Wait, isn’t this man a con artist?! * * * Meanwhile, Carcel, Duke Lakan and Marquis of Rivandel—a lifelong bachelor who had just fallen for Asha at first sight—was deep in thought. ‘A natural appeal of wealth. Good.’ He also vowed that he would make Asha’s heart his own at all costs! Just as he was finally about to reveal the identity he had been hiding behind his Marquis title… “Actually, Asha, I am Carcel La.” “It’s a relief that you only share the same name as Duke Lakan! Ugh, if it had been that terrifying man, I would have already died of a heart attack.” “It is definitely not Khan.” He made a vow. ‘I must never be found out until this marriage is finalized.’ The misunderstandings and seductions of two lifelong singles become entangled on a spring day. Will their love truly be able to come true?
