She was a low kapok growing in his back garden, and she fell in love with him at first sight.
She desperately absorbed the sunlight and worked hard to grow just for him to say "good tree."
After meeting him, she realized that there really was such a person. No matter whether it was a hundred years or the year before, no matter whether he lived or died, she could not stop loving him.
She misses him deeply; she loves him so much that she can't stop.
