It is a serene contemplation through the journey of each pilgrims and their own stories (if not complaints :'D ) to the endless forest; which I assume as the methapor of living (mostly harsh and stressful) life, where everyone has their own pace and perspective but too focus in walking to the same mysterious direction that somehow they didn't appreciate their environment (the birds, the blinking grass, the deer in front of and behind the scene, and the caravan).

And it's such a sentimental movement that the MC has her own identity, enjoys her journey as recalling each part of the forest with blurred but loving memories, and finally finds the way out of the confusion :')
