Seijo wa Isekai Onsen de Midara na Ouji-sama ni Dekiai Saretemasu

Who would have thought she'd be embraced by the man of her dreams in another world?! A dull hot spring girl devotes her body and soul to a prince in another world...!! Her boss, Sakuraba, is always cold towards Seira. She has fallen in love with Sakuraba since their job interview, and spends her days just staring at him. One day, when she prays to the god of love at a shrine for love to come true, she is transported to another world! There, Seira becomes a princess, and reunites with her idol, Sakuraba, as a prince...!?
