Back then, Lily Grant made a clever decision... to advance by retreating!
When Lady Morgan issued the order for her to leave, she didn't take the ticket. She just said with tears in her eyes, "I know. I'll explain it to Lucas... it's just that I met him too late."
That night, Lily Grant packed her things simply, and even though Lady Morgan repeatedly said she could leave the next day, Lily insisted.
Furthermore, being "considerate," she didn't leave through the front door but snuck out through the back.
Lily's insistence on leaving had a reason... she needed to make Lucas Morgan anxious!
In the Morgan family, all she could rely on was Lucas's deep affection for her. She clearly knew that only Lucas would protect her at all costs.
If she left the next day, everything would be too calm.
She had to leave secretly before the banquet ended so that Lucas would look for her, would find a way to know what had just happened.
