Hyunjin works for a "Boyfriend for Rent" app. He's used to clingy clients, dramatic fake dates, and endless selfies. So when Felix books him for a whole day... just to sit in silence while he studies, it's confusing. And kind of nice. Maybe too nice.

Lee Felix has a secret crush on Hwang Hyunjin and messages him every chance he gets. Hyunjin just finds him annoying and always responds with something dry or mean.

When a scandal threatens to expose everything, will Hyunjin finally drop the act and show the world who truly has his heart?
