Transmigrating to the 1970S: He's as Purehearted as They Come

My new novel is out! You're welcome to read it on Tomato Novel. I hope you'll enjoy it. Your support is what keeps me writing, and I'll do my best to tell every story well! Her wicked stepmother wants to marry her off to a man in his fifties, and her fiance actually expects her to bid against another woman for him? Whoever gives him more money and treats him better gets to marry him? What makes you think you're so desirable? You're ugly and promiscuous. I'd have to be a complete idiot to bid on a turtle like you. If you're going to be cruel, don't blame me for being ruthless. Watch as she empties the savings her family has hidden away for years, cuts off everyone holding her back, and sets out into a vast world where she can soar like a fish through the open sea and roam wherever she pleases. * One "Big Sister" is all it takes to save me for a lifetime. In the 1970s, she hunts enemy agents, works as a translator, dives into the water to save people, builds machines, and takes the underworld by storm.)
