I sat on a bench in the park and watched the passers-by; you walked by the cherry trees in the park and stared at the end in front of you. I remember, full of memories, you forgot, leaving only the back. Never say "no regrets in life" when you are happy. Life has never been as simple as a piece of chocolate. Some flavors do not exist in your memory, but once they appear, you have to bear the endless aftertaste.
