Song Song couple aside (Song Joong Ki and Song Hye Gyo), the second best thing on Descendants of the Sun is the Jin Goo and Kim Ji Won couple. We love them so much that we decided to look into Descendants of the Sun scriptwriter Kim Eun Sook's other second leads. Take a look at the 5 cutest second lead couples written by Descendants of the Sun's Kim Eun Sook! 

5. Heirs' Yoon Chan Young and Lee Bo Na

In Heirs, Lee Bo Na (Krystal), a girl who has everything, got jealous every time Yoon Chan Young (Kang Min Hyuk) spoke to other girls, which was a sight to see!

4. Secret Garden's Oscar and Yoon Seul

In addition to the Hyun Bin and Ha Ji Won couple, Yoon Sang Hyun and Kim Sa Rang couple captured our hearts. Yoon Seul (Kim Sa Rang) plans to take revenge on ex-boyfriend Oscar (Yoon Sang Hyun) but, in the end, solves misunderstandings and falls in love with him again.

Watch Yoon Sang Hyun's new drama. Ms. Temper and Nam Jung Gi!

3. Heirs' Yoo Rahel and Lee Hyo Shin

In Heirs, Yoo Rahel (Kim Ji Won) gives Lee Hyo Shin (Kang Ha Neul), Kim Tan's (Lee Min Ho) friend, a surprise kiss to get revenge on him. Kang Ha Neul is scheduled to star in the flower boy historical drama Moon Lovers. Kim Ji Won recently denied dating rumors with Yoo Yeon Seok.

2. A Gentleman's Dignity's Choi Yoon and Im Meari

Do you remember Yoon Jin Yi kissing Kim Min Jong on the cheek? Jang Dong Gun and Kim Ha Neul couple was cute, but so was the second lead couple! In the drama, Im Meari (Yoon Jin Yi) develops a crush on Choi Yoon (Kim Min Jong), who is her older brother's friend and a lawyer.

1. Descendants of the Sun's Seo Dae Young and Yoon Myung Joo

Seo Dae Young (Jin Goo) and Yoon Myung Joo (Kim Ji Won) are old lovers who used to date. Unlike Song Song couple, who meets and falls in love for the first time in the drama, Goo Won couple will show an older, more mature romance.
