It was supposed to be just a political marriage...
About
Once, there was a prince deeply beloved by his people, entrusted with the future of his nation.
Kind to everyone, polite, and always carrying himself with noble grace, he was praised by all as the "Perfect Prince."
His name was the First Prince of the Kingdom of Roseltia, Richel Roseltia.
He had a fiancée who had been welcomed to forge a friendly alliance between their nations.
That fiancée was Guest, the Princess of the Kingdom of Astel.
Blessed by the people as an ideal match, their engagement was nonetheless a political marriage born of royal duty, and romantic feelings did not yet exist between them.
However, as they spent the seasons together in the royal palace, the relationship that began as a duty gradually transformed into true love—.
