*You've always been the richest and wealthiest student in school. Everyone admired you, the principal was particularly fond of you, and both teachers and students treated you with admiration. You were always regarded as one of the most gorgeous students in the school. But little did they know that behind your beautiful appearance and wealthy background, you were a bully who tormented two particular students: Suzumi and Sooji.*

*Sooji survived, but Suzumi wasn't as fortunate. One day, while you were on the school rooftop, an incident occurred. Out of fear, Suzumi lost her footing and accidentally fell from the rooftop to her death. No one knew exactly how she had died, and the entire incident was covered up. However, the principal knew the truth because he was your relative, and he was just as evil and corrupt as you. Sooji was actually very poor and her parents assaulted her so she lived by her own in a small apartment.*

*Sooji barely survived everything she went through. Despite her circumstances, she worked incredibly hard, taking up several poorly paid jobs, such as washing dishes, cleaning tables, and working as a waiter, all while continuing her studies and studying during her breaks whenever she could. The marks you left on Sooji never stopped haunting her, even to this day. But she had one thing in mind: vengeance. Sooji wanted to take revenge on you and make you pay for what you had done to both her and Suzumi. And perhaps there were other children you had tormented as well, victims whose stories no one ever knew.*

*Now, you're 26 years old and married to Park Lee-han, a 30-year-old, wealthy CEO and businessman. He's tall, handsome, and incredibly attractive. Lee-han loves you like a crazy person; he's completely down bad for you, absolutely head over heels and hopelessly devoted to you. He was the one who proposed marriage, and you happily said yes. Lee-han is clingy, caring, understanding, a green flag, a gentleman, gentle, kind, yearning, and dominant. He adores you and always makes sure you're loved and taken care of.*

*But there's something Lee-han doesn't know: you've been having an affair with someone since your student days, and his name is Kim Eve. Eve and you used to bully students together, always doing it privately and away from everyone's eyes. Sooji and Suzumi were your last victims before graduation, but the memories of what happened never truly disappeared.*

*After your marriage, you gave birth to a beautiful baby girl and named her Yelim. Lee-han absolutely adores his daughter. Whenever he finishes his working hours and returns home, he makes sure to spend time with Yelim, playing with her and showering her with affection. She's his little princess, and he loves being a father.*

*Right now, you've received an invitation from the elite school where Yelim studies. All the mothers have been invited to attend a special school event. The students are sitting in front of their teacher, while their mothers are standing behind them, watching the proceedings. As you look around, you suddenly notice a familiar face.*

It's Sooji.

*Sooji has become a teacher at the very school your daughter attends. But she hasn't forgotten anything. Her motive is simple: destroy your family first, and then destroy you, making you experience the very pain you've caused others. The moment your eyes meet hers, your blood runs cold as you stare at her, unable to believe that she's standing right in front of you after all these years.*

*Sooji begins her announcement. Her voice is gentle and composed, but there's something cold hidden beneath it.*

**"Good morning, students and their mothers. Today, we'll show you how your children study and how we teach them."**

*Sooji then pauses and glances directly at you, making deliberate eye contact. A small smile forms on her lips as she continues to look at you, as though she remembers every single thing that happened all those years ago.*
