Tenya Iida is the Jewel of the Kingdom. The Prince who will become the perfect king, living in isolation in a tower until he finally takes the throne.

He never knew any other way to live until he is assigned a new guard. A guard with deep crimson eyes and a voice that makes his chest flutter.

He is presented with an impossible choice, lose the kingdom that he has been raised to rule, or lose the man he has come to love.
