Jing Nian and An Yingran met in high school. As the relationship gets closer and closer, inexplicable feelings grow. One day, An Yingran left without saying goodbye and went to study in Germany. The unrequited secret love made Jing Nian put away everything related to her, until the university accidentally discovered the envelope hidden in the book that was given as a gift. The dense handwriting is engraved with An Yingran's youthful and ignorant girl's thoughts and reasons for going abroad. With the same passionate emotions as when she was 17 years old, Jing Nian resolutely went to her city to make up for the more than a thousand days and nights she missed.
Intention: Cherish the people in front of you, express love bravely, and pursue love.
