Viola, the daughter of a viscount, was determined to break her engagement with Philip, a duke, as it would only bring her hardships. So, after an accident, she devised a plan to fake amnesia. But to her surprise, Philip claimed that they were in love before, saying things like "You used to call me Phil when we were alone." Caught in a tangled web of lies, Viola struggled to maintain her charade of memory loss.
