Korea Days with Sungjae

Yook Sungjae is about to debut with a group called Phoenix under CUBE Entertainment. There he meets Keithlin Joy Willows, an aspiring singer/songwriter, who has also been given her first big break. If she aces her new job as Hayes's manager while their debut, which means making sure he is on time, knows his lines, and doesn't get himself into trouble, the CEO of the company will make Joy a trainee in the entertainment.

The only problem? Ever since Joy met Sungjae, she already had a crush on him. She has to keep her emotions in check, impress Sungjae, and add some heart to her singing and songs. But what about Joy's heart? Does Sungjae feel the same way about Joy as she does about him?
