Billionaire, software mogul, Adam Pi has everything in life with the exception of positive memories from High School. He begrudging goes to the 20th reunion and has such an amazing time he finds himself wondering "If I knew then what I know now" and offers the entire grad class one year's salary to come back and do one more month of the 12th grade.。本剧以1999年澳门回归为背景,人物命运的变化正是澳门回归前后社会生活的一个缩影,以唐家的几个人物命运、事业、爱情、亲情、友情的纠缠为主线,构成了全剧曲折生动故事,剧情让人产生人生反思,从而走向人性回归。。
