A story of a manipulative woman and a cruel love affair. The seemingly innocent girl, actually cunning, kisses someone else in front of him, making him jealous without any real connection. Dumped by her childhood sweetheart, she returns from studying abroad to seek revenge, transforming from a good girl into a wicked one. She becomes a womanizer, indulging in promiscuity, smoking, and drinking, and every substitute she finds resembles him. She dreams that he asks her if she loves him, only to wake up to find him lying beside her. Hitting him becomes a reward. Her best friend asks if she remembers him. She says she doesn't, but her friend says she hasn't revealed who that person was. Yes, when you love someone, even the shadows of their substitutes surround you. Even during her time studying abroad, she still thinks of him. How can one forget the one they love most? How long does it take for a devoted person to become a manipulative woman? Just the moment he dumps her. She changes, but her manipulative behavior is only superficial. He still takes her virginity. She says she wants to kiss a male model. So he can be jealous too. Where was he before? Did he love her? She doesn't know. If he loved her, why did he dump her so cruelly back then? The seven-year itch is something no one can escape, right? His childhood sweetheart became a CEO, and he begged her to have their child to tie her down. Could a person be so cruel? He didn't want to use a child to bind her; he tried to keep her by his side forever, unaware that she had changed. She had nightmares about him abandoning her, yet he held her and said he wouldn't leave. Upon waking, her instinctive reaction was to slap him. Was it that being too greedy meant she could never have the one she loved most? Little did she know, she called him crazy, but he said he wouldn't be crazy if it weren't for her. He grabbed her neck, asking if she had been with someone else abroad. She felt his jealousy, which gave her a sense of triumph. He smashed the phone her mother had bought as a keepsake. Having missed her mother's funeral, she began to hate him. She replaced his male assistant and secretary with his stand-ins, provoked him by having unofficial relationships with them, and even kissed them in front of him. He was furious and extremely jealous. Their relationship was never officially announced, yet she was consumed by jealousy over their lack of recognition. Watching him be jealous, she felt a strange sense of vengeful pleasure, but she used foreign etiquette to provoke him. He had nowhere to vent his anger. He said he wanted to kiss like that abroad too, but she said enemies don't need to kiss. He was enraged... His face turned green as he forbade office romances, implying that only he and she were permitted to have one—a double standard. She skipped work to meet her younger self at a party hosted by the school's most popular male model, but secretly hoped he'd catch her. She kept wondering why he hadn't arrived yet. Finally, he came, but as she tried to open the door, she regretted that he had prevented her from seeing her mother one last time. Some hatred, in the face of love, only brings pain and distortion. Torn between two people she loved most—her beloved mother and the man she loved most—she agonized over the regret of not seeing her mother one last time; the dead cannot be brought back to life. He was alive, so she had no regrets. But her mother couldn't live, and she couldn't forgive him. Even when the male assistant wanted him dead, she hesitated and agreed. He said she was heartless, unaware that he was even more heartless when he dumped her. She was merely repeating the actions she had taken when dumping him. The male assistant also smashed the wine glass her mother had left behind, yet she didn't see him as an enemy, only heartache and hatred. This made her resolve to join forces with the male assistant to kill him, but love made her hesitate about telling him the truth about his impending death. She bitterly thought, wasn't this the best opportunity for revenge? Yet, she felt he didn't deserve to die. People are always caught in a dilemma when making choices; the contradiction seemed to make either choice unhappy. But she didn't understand what the male assistant meant by what he said. Wasn't he clearly dumped her because he didn't love her? Why were his words so light and so heavy?
