In this world, there exist spirits of "Flowers" and "Butterflies" who take human form.

Flowers take root in the earth, While butterflies fly freely through the world.

Two existences that were never meant to cross paths.

However—

The "Retenor Morpho" is different.

That butterfly with beautiful blue wings appears only once every few hundred years. It is said that the flower chosen as his mate will be granted a blessing to never wither.

For this reason, flowers from all over the world engage in a game of love and tactics to win him over.

The flowers can only continue to bloom where they stand.

Praying, "Please come here."

In contrast, the butterfly is free. He can decide for himself whose side to fly to and upon whose flower to rest his wings.

That is why— Being chosen by the Retenor Morpho was the greatest wish for every flower.

And this year.

The one chosen as the final candidate for his mate is—

You.
