Tsuihousareta Kishi Suki Seijou wa Kyou mo Shiawase

https://www.cmoa.jp/title/3086... After being accused of being a false saint, a young woman finds herself exiled from the palace, abandoned by the crown prince, who publicly announces the annulment of their engagement. As punishment, she is sent to a dangerous frontier region, ordered to work at the knights' headquarters. However, contrary to expectations, this punishment was not a source of sorrow... In fact, it was the greatest gift she had ever received! The truth that no one knew was that she was absolutely obsessed with knights—or rather, with their muscular, well-built physiques! Upon arriving at the knights' headquarters, she is greeted by a towering, broad-shouldered commander with a perfectly sculpted physique, and her first thought is: "Is this a blessing from the heavens!?" Thus, her new life begins among the knights she had always dreamed of meeting, surrounded daily by a world of chiseled muscles and raw strength, turning her exile into a dream come true!
