The two people who were once close were forced to separate due to an accident. Reunited many years later, each of them is the "remaining warmth left after burning to ashes" in each other's relationship. They want to get closer but are afraid of being burned again, so they can only look at each other from a distance through memories. In the end, even the remaining warmth became a thought that could no longer be touched.
Purpose: To explore the eternal pull of love and regret under the weight of fate and reality, and how to survive with the remaining warmth after loss.
