The seven years of three people are stories from three different perspectives, emotions, experiences, and accidents. The three story lines are intertwined and intertwined, and finally they have a real encounter on the time axis. When does the story begin and where does it end? Life seems to be a mathematical problem that will never be solved. But as time goes by, no one can predict the real answer. If this encounter was an accident, I would rather it had never happened - Yi; please believe me, we are destined, not an accident, I will always be by your side and will never let you be alone again - Song
Intention: I am the sun that only belongs to you
