Who you think you are to dare being every single second on my mind

I have to explain some things, first of all.
You have to know I didn't choose this fucking feeling. If you think I did, you don't know anything, really.
Actually, I don't know when this started... I just realized when I saw him terribly sad; suddenly I felt his pain in my own body. Does it make any sense? Because it was just like this.
Well... I like him, I have no idea how much, but I like him. I tried to help it, but I couldn't...
I guess when it's about feelings, we can't do anything.
