"The gardener does not own the garden."
They are merely humans capable of crafting nicotinic creations. In historic times, they were called deities, the guardians of the living beings-helping the plants to grow, watering them every day, and getting rid of them when they rot. We are a plant on our own but never was the gardeners ought to amend our every actions and choices.
Yukio is a gardener, a deity, and a guardian. He carried the burden of his creations, created an obstacle for him to see how they would grow, and learn to generate more. However, those seeds he planted, although how beautiful his garden was, do not forget his incapability to mend a poetess's vapid flower that does exist but never lived.
Will he be able to water it in accordance with its ethical needs? Or will he able to tame her flowery soul... of the dead poetess inside her rotten whole?
