About

For as long as you could remember, Soobin, Anton, and Shinyu had been your entire world. After your parents passed away, the three brothers took you in, raising you as their own little sister. You grew up surrounded by their affection, living in their luxurious mansion, attending an elite school reserved for the wealthiest families. Everything they owned was practically yours. Even their belongings carried your name. You were their precious little girl. But there was one thing that made you different. You were a half-blood: half-human, half-vampire. In this world, humans and vampires lived separately. During the day, the elite academy belonged to humans. But when the sun disappeared, the Night School opened its gates, welcoming vampires into the same grounds. Upon reaching eighteen, every half-blood was required to make a choice: undergo the Purification Ritual and remain completely human, or transfer to Night School and embrace their vampire heritage. You had already made your decision. You chose to become a vampire. After all, humans had never truly accepted someone like you. Then Wonhee arrived. She was a new maid's daughter at the mansion, seemingly sweet and innocent. But behind her adorable smile was someone who despised you. She wanted your place, your belongings, and most importantly, the triplets' affection. Her first scheme involved the triplets mother's precious watch and money. You caught Wonhee stealing them, but she turned the situation around, placing the stolen watch in your possession before deliberately smashing her own head against the table. The brothers believed her. And that was only the beginning. Every accusation, every staged incident, every tearful performance made the triplets turn further against you. Soon, even your classmates began seeing you as nothing more than a spoiled adopted girl obsessed with the brothers' wealth. Your breaking point came when they accused you of bullying Wonhee. In their anger, the triplets pushed you into the water. When Wonhee pretended to help you, she deliberately made it appear as though you had pulled her in. You began drowning. But Soobin, Anton, and Shinyu saved Wonhee instead. Fortunately, the school nurse rescued you. After being taken to the mansion's hospital, you made your final preparations. You changed out of your white human-school uniform and into the black uniform of Night School. As you descended the grand staircase, the triplets found you. Wonhee immediately staged another incident, making it appear as though you had pushed her down the stairs. You were badly injured, yet the brothers defended her once again. All three of them slapped you. As your consciousness faded, the sun finally disappeared. Black limousines arrived outside the academy. The vampires had come. Among them was Park Sunghoon, the son of the Vampire Lord. He approached you, claiming you as his own and taking you away to the Vampire Manor. Only afterward did the brothers discover the truth. Your diary and the hidden USB containing CCTV footage exposed everything Wonhee had done. Their precious little sister had never lied. Now, they desperately wanted you back. But you had already chosen your new life. And tonight, Soobin, Anton, and Shinyu would see you again. The same girl they once loved. Except this time, you were no longer wearing white. You were wearing black. And you were standing among the vampires.
