Prologue

I know that he's no longer here today.

His regrets and sorrow had been remove in this world. He does not need to loiter around this Earth anymore.

I wished that I had never met him by any chance.

Right now, the pain that is within me cannot go away for long.

But I must get back on my feet and fight. No tears should be rolling down my cheek. He told me didn't he? That he would watch over me until he was reincarnated.

It felt like the past few months that I've been through with him suddenly disappears. It felt like he didn't exist but I KNEW that he was here, in front of my eyes only and not anyone else. Nobody would believe me if I told anyone.

I fell in love with a ghost. But he had vanished now. He disappeared. But he had always and will be, my guardian angel.
