KuENai Kishi-sama no Amaiki Seikatsu Shinan Kimi no Ii Tokoro, Boku ga Zenbu Oshiete Ageru

Camilla Hergrain serves as the vice-captain of the Thorn Company, an all-female knight order, and carries a persistent source of frustration: Frederik. As captain of the Second Knight Order and her childhood friend, he has evolved into an inseparable nuisance who constantly invades her personal space and treats her like a younger sister. Her patience is tested further when she intervenes to stop a delinquent soldier from harassing a maid. Humiliated by her sharp reprimand, the soldier challenges her to a duel that takes the unexpected form of a drinking contest. Before long, Frederik materializes out of nowhere and boldly inserts himself into the competition. Though Camilla is a remarkably heavy drinker and easily overpowers the offending soldier, the night spirals into a private one-on-one drinking match with Frederik at his residence. She awakens the following morning cradled in his arms, setting the stage for an entirely new kind of education. What ensues is a series of intimate lessons in desire led by the very man who drives her to distraction. This steamy romantic conflict pits a fiercely competitive female knight against a scheming, obsessively devoted childhood friend determined to claim her heart.
