Ricardo is but a young man who dreams of becoming a splendid gardener.

By day, he works as a helper in a lord's mansion, learning the basics from the gardeners who are his seniors. By night, he heads to a secret place where he deepens his bonds with a peculiar-looking friend. Switching between the normal and the abnormal, he was satisfied with his daily life.

One day, the lord's son singles him out to be his playmate. His enjoyable days as a helper were turned upside down, as he was slowly but surely forced into an uncomfortable life as a boring 'playmate'.

What was gained, and what was lost?

'Friendship' and 'promises' intertwine, and his daily life begins to be encroached on by a fruitless miracle.
