「I'm sorry, Lyla. Abby suddenly fell ill just before I was about to leave."

This was the standard excuse of Morgan, the Duke's son and fiancé to the Duke's daughter, Lyla, whenever he was late for their dates.

Morgan doted on his sickly younger sister, Abby, to an obsessive degree, and never doubted the validity of his excuses.

Even when Lyla wasn't angry, if Abby cried, claiming Lyla had upset her, Morgan would believe her and blame Lyla. Still, because Lyla loved Morgan, she patiently endured it.

But.

A certain incident caused Lyla's love for Morgan to cool completely.

"—I wonder why I ever loved such a man."
