Good guess I think either she will be blamed or this will be used for the crown prince to take interest in the mc and become one of the many love interest. And watch the crown prince is going to figure out she can see ghosts or make her spill to save herself.
Oh I ABSOLUTELY think that will happen... Hmmm. She had said he likes to prank her. OOOOH! I wonder...I think he's gonna pull a:
“I'm going to arrest YOU for this; however if you marry me, it would prove your innocence” move. After all, it would be crazy unlikely for someone who would want to harm and upset the prince, and ruin his birthday, to agree to spend the rest of her life with him
She is going to be blamed for the whole thing because right before it happened, she told the prince it would. I was telling at my screen the whole time, lol.
