My Dear, Prince

IN THE MIDDLE OF REPUBLISHING, PLEASE BE PATIENT

In a city on a mysterious island, big enough to be called a country, but small enough to not be seen. There was once a family called the Theerapanyakul family, who were the kings and princes of the island, that they call, Beige. You may ask "Why?", the answer is that the founder of the island, billion years ago, was once named Aurora Beige.
Myth has it, that she had some power of power, the shape of some sort of animal or something exotic, that allowed her to build a castle, make a kingdom, and find love. Until her powers were passed down to the Theerapanyakuls. And rumor has it, that she had only found her lover when she saw a birthmark of the same creature that she has, and it is confirmed, but they don't dare search for it, or they will disappear.
They said that she used her power for the greater good, but now, the passed down powers were started to be used for the worst, until one day, a boy and his brother got thrown into the castle, for god knows what.
One was assigned to accompany the next king, one was assigned to accompany the current king. Kimhan Theerapanyakul was said to be the cruellest king of all, never showing any expressions nor mercy, and finally found his weakness. The boy, Porchay Kittsawad, was his weakness.
Kimhan decided to soften up only for him over time.
Until one day...
