"I know that a simple 'sorry' can't fully resolve this issue. The harm you spoke of may be something I can never mend in this lifetime, but did you know? Over the years, I was truly sincere towards you. Yet, when I was most sincere, you thought I was lying to you. It was then that I realized no matter how genuine I was, it wouldn't necessarily gain me your trust. Just a single injury, over and over again doubts, doomed me to never be able to be with you!
Did you know that during all these years with you, sometimes I felt truly happy, and other times very sad? I'd often nostalgically remember every path I once walked with her. Avoiding, afraid to look at every road, every footprint, I've taken with him. I was scared that as soon as I opened my eyes and saw that place, I would remember how he and I had walked hand in hand, smiling happily on the street, chasing after... Do you understand? That feeling is truly indescribable!
