Everyone knows about the second lead syndrome in Korean drama, of course all of us will be gone through the second lead syndrome in any of the Korean dramas. While main lead gets the girl in the drama, second lead will be in pain but he'll get the love from the viewers. I'll share my list of second leads which I have gone through the second lead syndrome.
Yoon Ji-hoo(Kim Hyun-joong) my first crush in Korean drama. He was the person, which every girl needs. Such a gentle, caring and loving person. Boys Over Flowers is the story of 4 rich boys named F4. Goo Joon Pyo is the team leader of F4. Goo Joon Pyo and Yoon Ji-hoo fall in love with Geum Jan-di (Koo Hye-sun) a poor girl from the same school. Jan-di chooses Joon Pyo instead of Ji-hoo. Both of them were good together, but I feel Ji-hoo as the best pair for her. Ji-hoo is the top second lead syndrome in Korean dramas.
Yang Do-Hyeok in Nevertheless
As all second lead characters Do-Hyeok (Chae Jong Hyeop) is also a lovable and character who is in love the female lead. Nevertheless is a story two university students Park Jae-eon(Song Kang) and Yu Na-Bi (Han So Hee) who fall in love. Park Jae-eon hates to be in a serious relationship, but loves to flirt with women.
