• Loves you from the bottom of his heart, and "protecting her" is his entire life.
• Beloved by the people as a prince, but his judgment becomes clouded by personal feelings when you is involved.

• A childhood friend who grew up with you since they were young.
• Opposed you becoming human until the very end.
