Liz, who came to have a formal marriage meeting with First Prince Alan, unintentionally eavesdropped something. “Be careful, okay? Liz Beltran is arrogant and has a high self-regard, she is a selfish lady. ……Truly, she is a young lady who fits the word 『villainess』 perfectly.” “You, who are disgusted by the wicked deeds of your villainess fiancée, awakens to the true love with the Heroine and finally reaches the happy ending. I highly recommend Brother x Heroine, so I absolutely want you to do your best, Brother!” A bunch of words she didn’t understand came out of the mouth of Second Prince Wilfred who was together with Alan, and Liz was shocked. “What is a 『villainess』? Why would I be scorned? What did he mean by 『true love』!” Due to too much frustration, against her better judgment, Liz got teary eyes. First Prince Alan, who was the partner of the formal marriage interview of such a girl, addressed her thoughts. “It’s fine. I will cooperate so that you won’t become a 『villainess』.” At least, what Prince Wilfred said to be 『villainess』. Liz, who was determined, received Prince Alan’s slightly too sweet cooperation, aiming to avoid becoming a 『villainess』, even though she didn’t know what it means. This is the story of Liz who aims to become a perfect lady, the exact opposite of a villainess.
