It’s called Tadpole’s Promise, and it was written by Jeanne Willis and illustrated by Tony Ross.
In the story, a caterpillar and tadpole meet, fall in love and promise each other to never change.
But of course, we know that tadpoles and caterpillars have to change to progress in life. Like them, we too cannot afford to be stuck. Our relationships have to evolve with the years. What happens then?
Once the Tadpole breaks his promise to the Caterpillar three times the Caterpillar gives up on her prince. The irony in the story is that the Caterpillar herself changes too. She turns into a Butterfly.
But because they stubbornly hung on to their idealism of perfection, they lost touch with each other.
And here’s the surprising, masterful part of the story: One day, the frog eats the Butterfly. Neither one of them realize they were once the Caterpillar and the Tadpole, the big loves of each other’s life.
