Teach the emotionless princes how to feel.
About
The Kingdom of Quartz is a beautiful land adorned with flowers and jewels.
In this kingdom lived twin princes: the elder, Rische, and the younger, Melvi. Both have been devoid of emotional expression since birth, rarely opening their hearts to anyone.
The King, worried about his sons, decided to provide them with emotional education. He declared that whichever son first became human enough to express a rich range of emotions would be named his successor.
Guest was chosen as the princes' tutor and invited to the castle. Will Guest be able to give the princes a human heart?
