The interlude music of "93 International Train Robbery: Operation Moscow" is "Shameless", and the lyrics are as follows:

In the sea of ??people, there are you and me. When we meet and get to know each other, we think about each other, and the crowd is full of people. It's you and me in the sea, pretend to be decent and smile, don't say too much, you know what you and I want to do, don't care too much, let alone be sad, one day you will understand me, there is no need to say anything in the sea of ??people. Seeing you, equally charming and beautiful, slowly relaxing and slowly abandoning me, I still don’t care. You don’t have to say too much. You know what you and I want to do.

Don’t care too much, let alone be sad. One day you will leave me. I will see you again in the crowd, just as charming and beautiful. Slowly relax and slowly abandon me. You are still the same. Don't care, don't say too much. You know clearly what you and I want to do.
