Previously, Kim Go Eun and Jung Hae In met briefly on the set of tvN's 'Goblin' as Eun Tak and Tae Hee oppa. Now, they've been cast as the leads of 'Joyful Music Album' - telling the story of a man and a woman who meet by chance, just like a song you hear by chance on the radio. Over time, the two repeatedly stumble through chance meetings and missed opportunities, getting to know each other. 

Filming for 'Joyful Music Album' began earlier this month, and the production is set to premiere some time next year.
