What business does a lemon tree have among one hundred and fifty-four orange trees? But, can one choose where to be born, where to grow up, and with whom?

Lemon is a lemon tree that lives in an orange grove and is bullied by them. Lio is a swallow that perched on her branches, smelled the scent of her flowers, and felt his heart beating strongly. He “extended his hand” to her, she trusted him, and accepted his help.

The result was that the lemon tree felt beautiful, useful, and full of confidence. The story of Lemon and Lio is a touching love story between a swallow and a lemon tree. Will this love be able to erase all the differences between them?
