Cannot believe that you’re not here by my side anymore. I still cannot believe that you’re not here to cheer me up anymore. Those times, those over-sweet memories you gave to me was awesome. I still cannot believe, you are the one that I loved the most, have to leave me here, not looking back at me, walk away through your every paths of your better future. I cannot believe that you’re not mine anymore.
Cannot imagine you’re there without me. You told me that I am your only one, and I have to be your bride. I need you here darl.
