If you are looking for a drama that has romance, action, comedy, and drama, then you should watch Descendants of the Sun. It is one of my favorite Korean dramas of all time and here are some reasons why:

- The chemistry between the leads. Song Joong-ki and Song Hye-kyo play Yoo Si-jin and Kang Mo-yeon, a special forces captain and a surgeon who fall in love despite their different professions and values. They have amazing chemistry on screen and their scenes are full of sparks and emotions. They make you root for their love story and feel their pain and joy.

- The supporting cast. Jin Goo and Kim Ji-won play Seo Dae-young and Yoon Myung-ju, another couple who face challenges in their relationship due to their military backgrounds. They are also very adorable and funny together and provide a contrast to the main couple. The other actors who play the soldiers, doctors, nurses, and locals also do a great job in bringing their characters to life.

- The plot. The drama is not just about romance, but also about the conflicts and dangers that the characters face in a fictional war-torn country called Uruk. There are many thrilling and suspenseful moments that keep you on the edge of your seat. There are also many heartwarming and humorous moments that balance out the tension and make you laugh and cry.

- The message. The drama explores themes such as patriotism, duty, sacrifice, loyalty, friendship, and humanity. It shows how the characters overcome their differences and work together to help others in need. It also shows how they cope with loss and trauma and find hope and happiness in each other.

- The soundtrack. The drama has a beautiful and catchy soundtrack that matches the mood and tone of the scenes. Some of the songs that I love are "Always" by Yoon Mi-rae, "You Are My Everything" by Gummy, "Everytime" by Chen and Punch, and "This Love" by Davichi.

Descendants of the Sun is a drama that I would recommend to anyone who loves Korean dramas or wants to try one. It has everything that makes a drama enjoyable and memorable. It is a drama that I will never get tired of watching.
