Aveluna is just an ordinary employee at a large art company, often overlooked and constantly ordered by those above her. Her life is full of hard work, non-stop, even though her heart is heavy with the loss of both her parents. However, one night, after extreme fatigue, she falls into a deep sleep that she has not felt in a long time — a sleep that seems to take her far from the real world. When she wakes up, Aveluna finds herself in a garden full of dandelions, but He was just in his room! How did she get there? Is this a dream or reality? And what exactly awaits her in this mysterious new world?
