My fiancée seems to be the dragon's turn, but I'll do my best to protect her with all my might.

"Would you not call my name once more?" When Grey, the second prince of the Kingdom of Jilia, burst into the royal library, there was a dragon race member wishing to be called by his beloved fiancée, Rielle. At this rate, Rielle might be designated as the dragon race's chosen one. The dragon race is the strongest species in this world. If one is chosen as the dragon race's selected mate, they will never be able to meet their fiancée again. In order to prevent his beloved fiancée from becoming the dragon race's chosen one, Grey makes a firm resolve.
