Su Nian, who passed away in a car accident, turned into a childhood-sweetheart system bound to Jiang Yi driven by her obsession. Her initial memories were fragmented and her energy was thin. Every time a youth past was unlocked, her light grew a shade dimmer, and when all memories became completely clear, it would be the time she completely dissipated. She accompanied Jiang Yi, who was stuck in a low point, to get through the senior-high third-year sea of questions and break through final-exam testing grounds. Their old candy jar was modified into an exclusive little nest, holding lost-and-found tenderness within its square inches. Crossing life and death to make this trip, she only wanted to watch him walk out of the darkness and walk through a life without her well.
