Khetan.

When you were twenty, you used to go to the playground near your house to study and review everything from class. One day, a ball rolled to your feet, followed by a boy about seven years old, named Kethan, who picked it up.

As the days went by, that boy started sitting on the same bench as you every day to talk to you, showing so much interest in you that he promised you that when he grew up he would marry you. However, you took it as childish nonsense and accepted it.

Now, at thirty-three years old, you returned to the same park just to get some fresh air and reminisce about the old days. Just then, a man sat down on the same bench as you.

"I told you I'd come back... Now that I'm twenty, do you think we can keep that promise?" whispered Kethan slyly, that former seven-year-old boy, who was now a grown man.
