What if Craig discovers that she is the assassin that he'd been looking for? And what if she discovers that the murderer she'd been looking for a long time is just beside her and that person is the one she trusted the most?

A story about a heroine as she experiences the ups and downs of a high school life while striving to finish her mission as a secret spy. But, is it really that easy being a secret spy in high school?

The new teacher gave the wrong medicine, causing a child to suffer sudden cardiac arrest and die after failing to receive timely help. My fiance, who was also the vice principal, forged evidence on her behalf and pinned all the blame on me. I was fired and reported by the child's parents. Due to insufficient evidence, I was acquitted. But the child's devastated parents broke into my home with a kitchen knife and hacked me to death, severing me in multiple places. My fiance chose to cover it up for them. He disposed of my body and even comforted the parents. "A life for a life. Let this be my atonement." When I opened my eyes again, I was back on the very day the teacher gave the child the wrong medicine.

Wake up, be fed poison, go to school and put on a show. Come home, have head knocked into the hardest thing available. Go to sleep and repeat. It's a day in the life for Kai Deneiro. Her solace is the many faces she hides behind and the performances she puts on for the world. When she's someone else, she is most loved. But, Kai has long since given up on any real notion of love. In her mind, it simply doesn't exist--not from her psychotic mother, not from her dead-beat, estranged father, and certainly not from the pretty boys with their flowery words. When she transfers to a new school, she runs into the most charmingly arrogant boy she has ever met, and things take a strange turn. When he runs into her wall of faces, he's determined to break it down and uncover the true her.

I've gotten abandoned by my parents one week after my birth. In order to survive, I quickly call whoever picks me up "papa". The bigshots who are here for the gathering swap glances with each other. "Whose child is this? If no one wants her, then I'll adopt her." "Put her down! She called me 'papa' first!" Since then, I have 99 dads. Other than the fact that I have an extremely boisterous family, I make sure to keep to myself for the next dozen years or so. That is, until I get bullied during my high school times. Viola Mariani, the most popular girl in school, and her lackeys corner me in the washroom. Then, they start ripping my clothes off me. "So, you're the one seducing my boyfriend, hmm? Since you want to be a whore that badly, you might as well show everyone your nudes!" Since the beating I've received is a lot worse than I thought, I subconsciously shove Viola down the stairs just to protect myself. When I wake up in the infirmary, my teacher, Marianna Pagani, lashes out at me immediately. "So what if she berated you? Are you really going to kill her for that? I want you to call your parents here! I'd like to see who on earth is capable of raising an idiot like you!" Panic seizes me by the senses as I cry and plead to her, "Ms. Pagani, please don't tell my dad about this!"

Pauline Ashby, my senior homeroom teacher, is extremely childish. She tends to decorate everything she owns in a childish style. Even the exam admission tickets she has prepared for our SATs are printed on pink paper. On top of that, she even pastes many cartoon stickers on them. "Pink is a great color! This color represents cute little girls like me! Just use these admission tickets when you're about to enter the exam venue! I'm very sure you'll definitely score top marks in the exam!" Upon realizing that Pauline is about to screw everyone over, I quickly call the head teacher. He rushes over and gives Pauline a good scolding before giving us the actual tickets, allowing us entry to the exam venue. Everyone in class completes their SATs at their own pace. In fact, my childhood friend, Caelum Thornley, and I even get into prestigious colleges thanks to our scores. But on the day our scores are announced, Pauline ascends to the rooftop while bawling like a baby. "I just wanted everyone to attend the entrance exam with cute pink admission tickets because the color can boost their mood! Why must Sienna tattle on me? "I did so much research just to pick out the prettiest shade of pink for everyone! I gave it my all to help everyone in the SATs!" As Pauline wipes her tears away with her sleeve, she accidentally steps on the hem of her long skirt, causing her to fall down the building. The next day, Caelum leads the entire class in tying me up and kidnapping me to the summit of a mountain, where they push me off the cliff. As such, all of my bones are shattered, and I die a painful death. "This is your fault for targeting Ms. Ashby! So what if we love using the pink admission tickets?" When I open my eyes again, I've returned to the moment Pauline digs out the pink admission tickets. This time, I choose to keep my mouth shut.
