I am told that I am a villainess who tears apart two people in love. Well then, I shall perform that role with all my might!

I have a younger sister, one year my junior, who is sickly. As for myself, I have been strictly educated as the heir. Well, you could say it's what you'd call a "family that only dotes on the sickly younger sister." I've read novels about oppressed older sisters like this in entertainment magazines. I do receive the bare minimum of care, so to speak. Living surrounded by my somewhat troublesome sister and the family and servants who indulge her— "I'm sorry, but I can't marry you. I've fallen in love with someone else." "I'm sorry, Big Sister. It's my fault..." In short, to them, I am the villainess who tears apart the two people they love... or rather, I suppose you could call me a wicked woman? "My girlfriend is pregnant with my child. As planned, I'm going to marry her and become her family's son-in-law." Oh my, what an outrageous revelation! Considering various circumstances—— I shall take on the role of the wicked woman who tears apart the two people I love... to the best of my ability! Taking a deep breath—— "You beast! Beast, beast! Beast! You laid hands on my beloved sister!? You forcibly assaulted my sickly sister who was bedridden!? Someone, anyone, tear that man, that beast, away from my sister!? Protect my sister!!" Well then, did I fulfill my role as the "wicked woman who tears apart the two people in love" adequately? The setting is loose. Published on Alphapolice and Kakuyomu.
