This drama is a masterpiece! Park Ji Hoon/Choi Hyun Wook/ Hong Kyung were amazing in this series. I was so happy to see Yeon Shin Eun smile with his friends after all he went through! It is all about friendship and the bond they had with each other. Everybody should watch it. OST is also amazing. The opening of this drama slays! Can't wait for the 2nd season! 10/10
