Watashi wo Oujihi ni Shitai no nara Mazu wa Anatatachi ga Shukujo no Otehon ni Natte Kudasai

Synopsis

The hellish (?) gender-reversal school life begins! Linate was proposed to by the crown prince. The future chancellor and the future commander of the knights all proceed to propose to Linate, but her answer is "no." After all, she doesn't feel she has the qualifications of a lady. That's it! She has to show these men how hard it is to be a lady. If they want to marry her, they must undergo a lady's education as well! (Source: Hifumi Shobo, translated)
