A Collection of Tragic Endings

A collection of angsty stories with various male and female leads, mostly with bad endings. Some have happy endings, too. All kinds of tearjerkers, guaranteed to make you cry until you can't breathe. I'm not that cruel, so I'll include a few happy endings, too. What is the greatest regret in life? Is it, “You were born before I was, and I was born after you had grown old. You lament that I came too late, and I lament that you came too soon”? Or, “There is a loquat tree in the courtyard, planted by my wife the year she died. Now it stands tall, its branches spreading like a canopy”? Or perhaps, “Ten years between life and death, we are lost to each other. I try not to think of you, yet I cannot forget. Your lonely grave lies a thousand miles away, with no one to hear my sorrow”?
