As the president of Ling's Entertainment, Ling Chen is known as the "Iceberg King of Hell" who controls the overall situation, but he is burdened with the family curse of turning into a black cat every month. After a transformation, he was accidentally picked up by Su Qingyan, an eighteenth-tier star, and became the "briquette" in her live broadcast room. Su Qingyan originally wanted to make some extra money by live-streaming masturbating cats, but she didn't expect that "briquettes"'s cute appearance would make her famous overnight.
Ling Chen, who regained his human form, signed a contract with Su Qingyan to hide his secret: he would help her reach the top of the entertainment industry, and she would keep the secret and continue to "raise" him. From then on, Su Qingyan worked hard in the entertainment industry during the day, dealing with the jealousy and slander of her peers, and turned into a "cat girlfriend" at night, taking care of the sometimes domineering and sometimes clingy Ling Chen.
In the intertwining of entertainment industry intrigues and sweet daily life, the relationship between the two gradually heated up. However, the conspiracy of competitors puts Lingchen's secret in jeopardy. At this critical moment, how will Su Qingyan protect her lover? How will this contractual love go from just playing around to true love?
