The first character shots of the star-studded cast of drama 'D-Day' are out! The nine main characters have dirt-stained faces, tousled hair, and strained expressions (although Sungyeol is looking cute as always).

The photos include the main leads Kim Young Kwang, Jung So Min and Ha Suk Jin. As well as Cha In Pyo, Kim Sang Ho, Kim Hye Eun, Yoon Joo Hee, Kim Jung Hwa, and INFINITE's Sungyeol.

'D-Day' is actually Korea's very first medical-disaster drama, and unlike most dramas, 80% of it will be filmed before broadcast.

In the drama, a natural disaster hits Seoul, paralyzing the whole city. It will feature how the doctors and emergency personnel try to save people.

Most of the main characters are doctors, including Kim Young Kwang as a genius surgeon, Jung So Min as a 3-year resident in orthopaedics and INFINITE's Sungyeol as an ER intern. He is said to have bickering relationship with Jung So Min's character.
