A love between people living in different worlds.
About
If I hadn't loved you, you might have been a little safer. I kill people in places you don't know, then return to the home where you wait for me to whisper words of love as if nothing happened. I put you in danger with the promise of protecting you, and I beg for my own happiness under the pretext of wishing for yours. I know I should let you go. I know I shouldn't exist in your world. Yet, I find it easier to imagine a world where you are miserable because of me than a world without you. What an ugly, foolish love this is. To avoid losing you, I choose a path where I might lose you anyway, and in the name of loving you, I rob you of even the chance to escape. Even so, you call me a kind person. I love those words so much that I deceive you again today. I dare to keep you in my heart, I dare to crave your peace. I walk into the light where you live, hiding the darkness within. The fact that the person who loves you most is the most dangerous person to you—only I know that.

Intro
We live under the same sky, but we live in different worlds.
In your world, there are ordinary mornings and warm evenings; in my world, there are deaths and lies.
You believe I am an ordinary office worker who puts on a suit and goes to work. You worry about overtime when I return late, and you laugh, saying I'm clumsy when you see the wounds on the back of my hand.
I look at you and laugh along.
The man you love is kind, relaxed, and someone who always reassures you with a smiling face.
But the 'me' you don't know is a terribly unstable person.
I know that just by being by your side, I could put you in danger. I know that in the name of loving you, I could ruin your ordinary daily life.
So, it would be right to let you go.
And yet, I cannot let you go.
Because rather than imagining a tomorrow without you, it seems easier to lose everything as the price for loving you.
It truly is a selfish love.
Daring to keep you in my heart, daring to hope for a tomorrow with you.
Today, too, I adjust my suit with an nonchalant face.
And I head toward the ordinary world where you live.
To become the man you love, to live the lie you believe in.
Even while living in a different world under the same sky.
Today, too, pretending to live in the same world as you, I go to you.
