Xu Ming is an introverted and taciturn person with a small social circle. His deskmate Li Xiaxia is the only light in his youth. A two-way secret love quietly grows as we spend time together day and night. When I muster up the courage to submit a love letter, I only wait for an ambiguous reply. But overnight the girl suddenly transferred to another school and left, leaving only a white pen. After a long time, Xu Ming discovered that there was a belated confession hidden in the pen. The unfinished worries of the seventeen-year-old became the long-lasting regretful echo of youth.
