Meet him, Soul and Dream

One night, she opened her eyes and become a granny's servant in the palace?! Surprisingly, it's only happen at night, when she enters her dreamland.

Looking into granny's memory, this granny was serving in the last prince of previous emperor's palace. Albeit he was born sick, when he was young, he's a cheerful child who treats other kindly. But now, his condition is getting worse, leading to death.

In short, he was dying and others let it so. No one paid attention to him and threw him into the abandon palace with lack of care.

As for the pity, she sneaked into his chamber at night as a granny, just to feed him some nutritious food, so that he could at least have a little strength to survive.
