Everyone has their own story. It may have the same beginning and different process, but the result may be the same.
If we hadn't made a vow at the beginning, wouldn't we have been separated? If we could be less naive, wouldn't we stop experiencing these sorrows? If I said, I love you, would you never leave again? …I know there aren't that many ifs, so we're doomed to suffer the consequences of it all.
Dear you, dear friends, don't look for me. If possible, please forget that I ever existed; if one day, I heal the wounds all over my body, then I will appear in front of you with the brightest smile, and you must promise me not to expect anything. I don't want to see your sad expressions of pity, please allow me to be selfish for once.
