The story of ordinary people without background or identity.
A sober and rational girl met a cold and alienated boy during her passive growth years. They had known each other since they were young, but it took them so many years to get to know each other.
For so many years, she was more like an invisible witness. Although she had always been clear about her position, her heart still throbbed and hurt when she heard him say, "It feels like you have been invisible for many years and finally showed up, but I haven't caught you yet."
Purpose: Record heartbeat and time
