Super Junior Kyuhyun is singing the main theme song of Ha Jiwon's comeback drama 'The Time We Were Not In Love'.

The drama plots the story of how Oh Hana (Ha Jiwon) and Choi Won (Lee Jinwook), who have been friends for 17 years, will find love after being beside each other for a long time. This is going to be Ha Ji Won's next drama after 'Empress Ki'.

Kyuhyun is expected to deliver melodies that would suit the relationship between the two with his emotional and charismatic vocals. The OST will be released tomorrow and the drama premieres on the same date at 10PM (kst).
