Su Nian, a top student at the Conservatory of Music, accidentally broke into the studio of composer Shen Shiyuan while working part-time as a piano tuner.
In the darkness, she mistook Shen Shiyuan, who was in a "fugue" state of creation, for a model, and accidentally took away his first kiss.
Shen Shiyuan, who was embracing the "Flower of Gaoling", felt as if he had found a treasure after that kiss.
When Su Nian participated in the academy's annual assessment, he discovered that he was the special judge with "veto power."
Shen Shiyuan made mistakes and gave her a "personal teaching" in the name of "professional guidance", and used this as an opportunity to arbitrarily intervene in her study and life.
On the grounds that he "disrupted my creation and stole my inspiration", he asked Su Nian to be responsible to him and tied her to him with an "agreement".
While he was clearing away academic and interpersonal obstacles for her, he also launched a comprehensive invasion of her body and mind with an almost paranoid possessiveness and an attitude that could not be refused.
