For Better or For Worse

The spunky Lady Dillion didn't realize she was the villain of a romance novel until she encounters Marquess Cedric. Seeing him jogs a dormant memory of the novel's plot, in which her beloved younger sister dies in childbirth after marrying Cedric. Determined to prevent this, Dillion marries him herself, but what fate awaits her when she knows he's meant to fall in love with the real female lead later? In this marriage of convenience, it seems nothing turns out quite how either of them expects...

Somehow, before the appearance of the female lead, I became the male lead’s temporary wife. Since things had already turned out this way, I decided to try my very best. However… “It’s so fortunate that someone like you became Cedric’s partner.” “... I’ll admit it. It’s a fortune that you were the one to become his wife, Dylan.” “It’s such a fortunate chance that you were the one to become the Lady of the Brighton House.” … I think I did too good a job. When Cedric’s destined partner arrives, I will have to leave. What should I do? To someone like that, Cedric had said this. “Would you have ever thought that the one I would fall in love with would be you?” ...Would you still say the same to me after the real female lead, Adeline, makes her appearance?
