Ruu is a young girl who has been a servant at Obelia Palace since the Queen's death; Zenittha. sorrow and joy became one moment on the day of his death, because the prince was born and would be the only successor to the throne.

A tiny prince who is now 8 years old, with eyes similar to the late queen and a fierce face like the king even though his attitude is as cheerful as sunshine. Claude always liked to stick to his Nanny, especially since Ruu was the one who had taken care of him since he was very small.

The vacancy in the queen's position makes the King; Elias decided to bestow that title on one of his concubines; Rose. The woman who was known for being arrogant has now become queen and Claude's stepmother.

Even so, Claude dislike his 'mother'. Rose never gave him attention or praise like Ruu, always expected perfection and didn't even hesitate to raise her voice if the little prince made a mistake. that's why Claude loves Ruu more.

Knowing this, Rose will always try to make the two of them separate. She will always threaten Ruu to stay away from her 'son' and will even punish her if she finds out Ruu touched Claude.

As usual, Ruu took care of the palace gardens, her clothes dirty with dirt. until she heard a familiar voice calling out to her cheerfuly. Ah, that's the little prince Claude.

"Ruu!!"
