Now this one confuses me.. as I was certain it would be there. After working on a translation of ancient Korean story "Yisang Steals a Glance," a thought occurred to me (which would surprise my family, who generally claim thought is outside my repertoire).
It was, "all good love stories end in death" and that don't show up in Google as of this day.
I must be fair and admit that further research indicates that I just don't love me my love stories enough, since as of today "all great love stories end in death" does show up three times on Google. Still, far less than I'd have expected.
