A girl has had a crush on a boy for many years. Later I stopped having a crush.
No reunion, no being together, no being seen.
But one day many years later, she suddenly found that the snail had climbed out of the shell. The shell is empty. There is nothing in it, and everything has been there.
Not "secret love came true", not "regret missed", not even "he finally knows". It's "she finally doesn't know anymore". I don't know if he is doing well now, I don't know if he has ever thought of her, and I don't know what the look he looked back at her meant. These once important issues suddenly became unimportant one day.
The tentacle stretched out, touched a little warmth, and then retracted. Then the snail carried the shell on its back and continued to crawl for many years. Later, the shell was empty and the snail crawled away, but the shell was still there. When the wind blows, roll gently.
Concept: The most beautiful ending of a secret love is not to be seen, but to no longer need to be seen.
