"One day, the end of the world came.
She and I, we are the last survivers.
In order to protect her, I locked her in the basement.
There is no food, no water, and of course she doesn't trust me at all...
What should I do, so we can find peace through the last time of our lives.
The choice of life and death;
Pain and contradiction;
Deep inside the heart, the dark desire;
And ... hidden behind, the secrets.
Faced with all this, I just want to shout out -
I will do my best to save her!"
