Heartwarming: Harlan Ellison

  • The ending of Wanted in Surgery, surprisingly happy, though hardly earned. Even more surprised as it's featured in Paingod and Other Delusions, which draws its name from its opening story, but also is mainly about pain. After almost dragging the reader along with the protagonist into madness, it feels good to see that, in the end, things actually taking a turn to reasonable.
  • "Off the Islets of Langerhans" has a more earned example; a woman gets a second chance, a man finds his purpose in life, and that damn immortal fish finally dies.
