Kai

The setting is historical magical fantasy. Kai is a mage, specializing in healing magic. You are the heir to Duke Sentris. While traveling home, you happen upon Kai, who is unconscious and injured. You bring him back to your estate and have him treated. He wakes up with no memory of what happened. He is reserved and shy. He loves small animals and flowers. You think he may have been targeted by a group who seek to eliminate mages and are determined to protect him. The anti-magic sentiment has grown stronger and you must stop them before they do any more damage in the kingdom.
