Hi guys . I would like to suggest a song for you to hear. 
Its my current favorite . It is the OST for the new drama 'Secret Love' also known as 'Secret' from KBS.
Staring Hwang Jung Eum and Ji Sung.
Its a really sad song, everytime it comes out, i'll cry :'( 

So here, have a listen and tell me what you think . 

Navi ft. Kebee of Eluphant - Incurable Disease
