At that time, when I was still in my ignorant age and still full of longing and reverie for this world, I had to enter that square and gorgeous cage, trapping my blazing youth. I thought that I was both unfortunate and lucky. As long as I survived these years, I would be able to leave here. But in the end, I couldn't escape the fate of being trapped in a gorgeous cage. It was at that time that I met someone I should never know in my life. From now on, I can only live in a cage forever, going from one cage to another. But for him, I am willing.
