Synopsis: Oppa is a Beast

“Is this little brat playing with me? Where did you get all that insolence from? And on top of that, you answer me like it’s nothing. Are you really trying to treat me like we’re the same age?” At five years old, Seo Yunwoo smiled brightly, as if she had tasted all the happiness in the world from a single piece of chocolate. At twelve years old, Cha Jihan took pride in being the almighty Superman who had brought that happiness to the little girl. That crybaby brat was noisy and annoying, but she was also pretty fun to tease. As cute as a rabbit and more entertaining than a toy… Because you’re mine. Yes. You’re mine. A dark, spiteful impulse awakened in him, making him want to torment her mercilessly and make her cry as much as he pleased. He was convinced that she belonged to him. That beast has returned.
