Inside the car, Carmen sensed my stare. Her cold voice snapped me out of my thoughts. "Have you stared enough?" Her expression was chilling, nothing like a typical fifteen-year-old girl. Her dark, eerie gaze sent a shiver down my spine.
Alright then. It's time to work my way into her heart, step by step. "Carmen, I've never seen a girl as pretty as you before. Are you really going to be my sister now?" I gave her a sweet smile, my eyes filled with admiration and longing.
Carmen turned to look at me, a hint of amusement flickering in her otherwise cold gaze. "You really want to be my little brother, huh?"

Seriously? I'm only ten years old and your dad just adopted me. Do I have a choice?
"Yeah! I'm so happy to have a sister who cares about me!" I faked a cheerful tone, then suddenly became anxious, lowering my head with reddened eyes and nervously twisting the frayed corner of my clothes. "But I guess you don't like me either. No one at the orphanage liked me; they all hated me ... "
Carmen was taken aback, stiffly replying, "I don't hate you."
I instantly stopped pretending to sob and threw my arms around her waist. "That's amazing! My sister doesn't hate me! She likes me!"
Carmen's body went rigid. The next second, she shoved me away, her dark eyes narrowing. "Get lost. Don't touch me unless I say so."

Yep, definitely a yandere. Moody as hell.
The wealthy man in the front seat laughed and told Carmen to get along with me. I knew this home was really just for Carmen and me. He was always busy with work, so only Carmen would be around. As long as I could get on the good side of this yandere sister, everything would be fine.
When we arrived at the mansion, the wealthy man told the housekeeper to set up my room next to Carmen's. And so, my mission to win over my yandere sister began. On my first day of school, I clung to her arm, crying, "Carmen, I don't want to be apart from you. I'm scared, boo-hoo ... "
Carmen saw my snotty, tear-streaked face, looking like a pitiful, abandoned puppy. Ultimately, she didn't have the heart to push me away. From that day on, I became her most devoted fan. I couldn't stop saying "my sister" with pride. When I was sick, I refused to take medicine unless she coaxed me. When I couldn't solve a problem, I'd ask her to teach me and if I got it right, I'd ask for a hug as a reward.
