So he probably promised you a castle and moments of shine.
You left souls, hearts, people, and life. Things that only you had but still for you it wasn´t enough.You had things that could make you go across the universe in seconds and hold you for several centuries, but only now you can see it. ...Now nothing is real, apart from your pieces on the floor, the lies he told you and the evil that is growing in your heart. You probably found a meaning for hate, and you want a taste of revenge...
There's nothing you could do now, the high that makes you feel right makes you see everything and you fall of your fantasy. The high that should keep you quiet for a moment show you in different colours how he is definitely not your prince.
