I PROMISE I WON'T LEAVE YOU
After Eun-Woo left for Jieun, Lia spent time with the other princes. They actually been there talking about the enemy and the result of King Liam and King Arthur first interrogation before. But stop that now as Eun-Woo suddenly leaves.
Ayana also had to follow the princess at this point, even though she was a little awkward there. She never spends time with all of the princes without Jieun before and of course she can get nervous. But the look from Haru who seemed to say 'its okay' made her calm down a little.
In silence, both Haru and Ayana are unaware that the princess deliberately did so so that the two of them could spend time together. She knew from the look in their eyes, even though no one told her that Haru and Ayana did have some feeling for each other and she, like what she always does, wanted to help even a little.
