On February 28th, Yoo Sung Eun and Kwak Si Yang from Mnet‘s Perseverance Goo Hae Ra released the music video for the OST track “Do You Know.”
As Yoo Sung Eun and Kwak Si Yang emotionally sang, “Do you know…how much I loved you, because tears came out again when I saw you,” the music video showcased Lee Woo Ri’s love interest Jang Goon as well as the love triangle between characters Kang Se Jong, Goo Hae Ra and Kang Se Chan.
“Do You Know” was originally released in 2011 by Jo Sung Mo. Since then artists such as Red Velvet‘s Wendy, INFINITE‘s Sunggyu and Woohyun have performed their own rendition of the ballad track.
