That night,
Queen Anna found it difficult to sleep. So, she decides to walk alone in a covered dress so that no one knows it is her, heading to the forest where Beom-Soo and Aera's graves are there.
Somehow she felt like being there even though it was already late at night. She didn't even feel scared there as the moon, there shone brightly illuminating her journey. And this is not the first time she did this anyway.
Soon she was walking, now she was back in the woods, looking at the two symbolic graves located there. Then she looked at the surroundings. Try to imagine things that once happened there. Although she did not witness it herself.
Yes. This place, is the place where Aera was killed by Liam long ago. No one knows about it. Anna also knows it from Adele.
