soundtrack interest of love

The OST was amazing and on par with the different scenarios, i especially loved "Shadow Love" by LAS, have been playing it repeatedly, it goes well with this slow paced drama, and the lyrics are amazing, i feel like it portrays Sang Su's love for Su Yeong more than the 2nd ML, Jong Hyeon's, where this song was always played, in the 2nd ML and . i give my first love to you . unconditional love
