Once there was a true love in front of me, but I did not cherish it.I didn't regret until i finally found i have lost it（这个时态没有错,失去已成一个一般的状态,延续到现在,所以用现在完成时）,but it was too late. Nothingcould be more painful（miserable）than this!If God could be kind enough to give me another chance, I would say to the girl that“ I love you” .If i have to（have no choice but to 觉得更好）set a deadline for my love,then, I hope it is ten thousand years.
