well, here's my interpretation:
The protagonist speaking might be an ex-criminal who decided to testify everything he knows to the police, or something like that, and therefore hes about to be put under a program of witness protection and taken away. During the whole album he keeps repeating it, "in some time I will change my name", "Im running away, I will never forgive myself for running away from you", "no one here knows my name".
Someone is obviously willing to take revenge, in fact someone goes to his girlfriends house ("he came back to your house/ I didnt take it as a promise
" ).
Hes taken away, they give him a new name, a new identity, they cut his hair short. He thinks back to when he had decided "to join in", he looks at a picture and remembers a scene from the past when he was abroad in a hotel room with his girlfriend and asks himself "what will replace us?", he knows he wont ever go back to her, but the contemplation of that possibility is always there, behind the corner.
In the song "One year from now" he wonders if he will be strong enough to bear it, he asks himself if, in one years time, he will dare calling her "mine".
In the last songs of the album, he decides to take a big risk and to meet a friend of his; with fear in his heart he goes to the meeting, always staring at the clock and expecting that someone could find him and kill him. He meets his friend, tells him hes traded all of his memories but he still remembers him well; they talk for a while, then its time for him to go away (or maybe someone had put some poison in his drink? Did the friend betray him?) and the last words he says are "my regards to the ones that I love, I miss them, tell the I love them I miss them". The song ends abruptly, meaning he 1) goes away and wont come back anymore, or 2) dies.
