Lin Xiaoman is a sophomore girl in high school. After being separated into liberal arts and sciences, she was plunged into darkness due to academic pressure, friendship gaps and the contempt of others. She was criticized by the teacher in class and made things difficult by the class idol in life. She struggled with low self-esteem. By chance, the sound of violins outside the window and the photography collection in the library opened the door to a new world for her. Encouraged by his friend Chen Yutong, Lin Xiaoman used a camera to record life, participated in a photography competition and won the first prize. Not only was he recognized by the violin boy on the opposite floor, but his studies also improved significantly. At the graduation ceremony, Lin Xiaoman finally accepted himself and embarked on a new journey with confidence.
