Can you think of some other ending for the story?

Explanation

The story could have ended on a more positive note. Instead of resigning from his job, Mahendra could have been shown as a real courageous man and proving the ghost theory wrong. Another ending can be of both Mahendra and Iswaran leaving the place together and in turn continuing their bond which is depicted earlier in the story. Iswaran has been explained as a man of all seasons for Mahendra.
