A Friend's Neighbor Dies When It Turns Warm and Cold

By chance, I met a girl on Douban; By chance, I had a romantic relationship with a girl; By chance, the girl and I parted ways; By chance, we have gone in opposite directions. Like a hyperbolic trajectory, we were closest at a certain moment, and then became farther and farther away, never to see each other again in this life.
