Second Lead Syndrome

Dramas that made me root for the second lead character (male or female) 

• Cinderella's Sister - Han Jung Woo (Ok Taecyeon) 
• Who Are You: School 2015 - Kong Tae Gwang (Yook Sung Jae) 
• Bridal Mask - Ueno Rie (Han Chae Ah) 
• Flower Boy Ramyun Shop - Choi Kang Hyeok (Lee Ki Woo) 
• Full House Take 2 - Won Gang Whee (Park Ki Woong)
