Good Friends: a friend you can lean on in times of trouble, you can laugh with and sometimes you can quarrel. It is given that you love your friend but what if it exceeds from the Philia type of love? Would you pretend to maintain the brotherly love you feel just to be called a good friend? When Sun Woo was asked what did he felt when he worked with Sera again and what can he say if it would circulate into a dating rumor he just vaguely said that a Good Colleague is a good friend, shutting down the dating allegation between them. After 5 years of not seeing each other would they still be good friends amidst the hidden feelings they have for each other?
