In the end, I am still alone. I am guarding this empty city that lacks you alone.

▓Guard an empty city and wait for an old person

An empty city, I chose to give up from the moment I met you.

On the other side, you and I are lonely in an empty city.

If memory is as hard as steel, is this a happy city or a ruin?

No matter how noisy a city is, without you, it is an empty city.
