Top singer Zhou Yubai appears to be a rebellious stage king, but in fact he has been secretly in love with his manager Shen Zhiwei for five years. He deliberately terminated the contract with the original company, lowered his value to sign a contract with Shen Zhiwei's just-started studio, and gradually invaded her life in the name of "training new people". He improvised love songs in the recording studio late at night to tease her eardrums, pretended to be drunk at the celebration party and bit her collarbone leaving a crimson mark, but pretended to be distant when she fell in love: "Sister, don't be responsible for me, I can't afford it."
