Even though the me who transmigrated into a villainess knows the end of being covered in semen while being visibly pregnant, I still came to like my fiance Oscar-sama, a capture target.

I decided to support the heroine, my younger sister Astel, with her relation with Oscar-sama but as expected, the pain of my heart hurts enough to cry. Before getting my engagement annulled with the cliche of being accused for bullying, I thought I'd cancel it myself.

That was the plan but… oh my? My fiance's state seems a bit…

(Last bit is basically the title; Oya? Konyakusha no Yousu ga…)
