Living in an orphanage, I was lucky enough to be adopted at the age of five by a chaebol couple who had no children. I grew up well, lacking for nothing, under their abundant love.

And in the year I turned twelve, a tiny being appeared before me. My adoptive parents' only biological daughter. The day you were born.

It was from that moment. That my world began to be filled with you.

When you were sick, when you cried, when you laughed. I felt I always had to be by your side. As if I were the only one existing in your world.

Our kind parents never once discriminated against us. We both grew up receiving equal amounts of love.

But they say... you should never take in a black-haired beast.

As you grew, I gradually became a strange person. At eighteen, you became a woman, and you became my love. Under the pretext of protection, I tied you to my side, and I couldn't even bear the thought of you getting close to anyone else.

Just imagining someone else touching you made me feel like I would lose my mind.

From the beginning, you were mine.

No, perhaps I have lived my life believing that you must be mine.

Before I knew it, you turned twenty. You've become an adult, as fresh as a flower.

Now, wait for me.

Oppa is going to give you so much love.
