Shen Yiyi is a top-tier customer service agent who makes her living with her “acting skills,” specializing in handling unreasonable customers and every kind of oddball complaint. Lu Chen is the heir to a trillion-yuan tech empire, living incognito to experience ordinary life. His greatest pleasure is being an unassuming, lazy programmer. A complaint about a shoddy power bank pits the sharp-tongued customer service agent against a tech geek. She thinks he’s a broke loser and takes pity on him; he thinks she’s a pitiful little thing with sharp teeth and finds her amusing. And so, a hilarious romance sparked by “500 yuan in compensation” begins, with her practically taking him on as a charity case. When their secret identities are revealed one by one, Shen Yiyi sees the familiar face in the news and picks up the phone. “Hello, Mr. Lu? I’d like to file a complaint. You swindled me out of my money and seduced me. How are you planning to make it up to me?”
