Due to an "accident" on campus, Gu Yan, a cool student in the Department of Astronomy, and Lin Che, a grass-roots student in the Department of Sunshine Department of Music, were forced to become partners in a campus observation experiment. The two people, who were originally incompatible with each other, went from dislike to each other to gradually understanding each other during a year-long forced relationship, and finally found that the other person was the person who could complete the other half of the puzzle of their lives. This is a story about growth, dreams and tender first love. In the starry sky and piano room of the university, two souls illuminate each other.
