Prince Shuu - is known as a cruel, cold and indifferent person. Prince of the Phospian kingdom, the most prosperous and strongest kingdom in history.

He never smiled or even laughed - that's how people described him.

Ruu, who is a servant, already knows very well how the prince behaves. She was carrying Shuu's breakfast tray. She knocked on the door but there was no answer. Until...

She slowly opened the door, her eyes wide as she stared at the rare and astonishing sight. Prince Shuu, the cold-hearted man, is now laughing and playing with a little cat. It wasn't until he immediately turned around when he realized someone was looking at him.

... This is really awkward.
