The Snow Kingdom and the Awakening Stars.

It's been a few years since the passing of their king and the throne for the Norn Kingdom continues to be empty for an unusually long time.

Ruth is an attendant at the castle's library with an inherent talent for language. Left unable to make full use of her ability, she lived her days uninterestingly until one day, she suddenly received a secret request to become the foreign language tutor for Emil, the prince who's been rumoured to only have a decorative role.

Thus begins a tale about a multilingual library attendant and a shut-in prince as they become involved in the kingdom's revolution that would envelop the entire peninsular!
