Adapted from a friend:
从前有个书生，和未婚妻约好在某年某月某日结婚。
到那一天，未婚妻却嫁给了别人。书生受此打击，一病不起。
家人用尽各种办法都无能为力，眼看奄奄一息；这时，路过 一游方僧人，得知情况，决定点化一下他。僧人到他床前，从怀里摸出一面镜子叫书生看。
书生看到茫茫大海，一名遇害的女子一丝不挂地躺在海滩上。
路过一人，看一眼，摇摇头，走了！
又路过一人，将衣服脱下，给女尸盖上，走了！
再路过一人，过去，挖个坑，小心翼翼把尸体掩埋了！
疑惑间，画面切换。书生看到自己的未婚妻，洞房花烛，被她丈夫掀起盖头的瞬间。
书生不明所以？！
僧人解释道：那具海滩上的女尸就是你未婚妻的前世。
你是第2个路过的人，曾给过他一件衣服。她今生和你相恋，只为还你一个情。
但是她最终要报答一生一世的人，是最后那个把她掩埋的人，那人就是他现在的丈夫。
书生大悟，唰地从床上坐起，病愈 !
My thoughts on this:
Life is like a bus on a journey. Some will alight at a point, some will board at another point. Indeed one might not have only one relationship but have to go through a few to at last find their true love. However, I believe it’s all worthwhile when you reach your destination. 
I hope R and sis’s E will realize this. Perhaps they are the second one to help us in our previous life, which is why we have shared memories with them as a couple. But C and sis’s W are the ones we are meant to be together, therefore in the end, to pei wo men zou dao marriage de are them.
