I got lost when I was 7 years old when my parents accidentally went on a trip and lost me. Having lived independently for 18 years and accustomed to a miserable life, I worked hard every day and became a successful woman. My parents are the richest people in the country and they found me, I was finally reunited with my family after all these years. I have an adopted sister. When I was lost, my parents treated her like their own child and took care of her with love and care. When I returned, my parents poured all their love and care towards me, her position was gradually taken away, there was less and less care and love from my parents for my adopted sister. The party to welcome me back quickly took place on a large scale, her presence gradually faded, that innocent, gentle, pure 18 year old girl could only stand quietly and watch it all.

"How do you feel, adopted sister?"

I entered the mansion's library room knowing she was hiding here, I wanted to see how she would react. Are you jealous of me or not? Do you hate me for taking back the position that was originally mine? Coincidentally, she was the one who saved me when I had an accident. It was thanks to her help that my parents found me.
