This is a solid drama. The acting, writing and characters are compelling. However I'm not sure why it's so highly rated on MDL; it didn't grab me and hold me like Goblin or The Untamed (and I tend to like slice of life dramas).

It's a bit like Korean Scrubs, but with perhaps a bit more attention paid to being medically accurate.

Many of the relationships seemed somewhat forced; Chu Min-Ha's crush on Yang Suk Hyung was cute and well acted, but I never truly believed that he returned her feelings, though I was happy the plot went that way. In general there wasn't enough romantic build up. Even though Chae Song-Hwa and Lee Ik-Jun were clearly compatible, it still somehow felt like they were settling; it was never explained why Ik-Jun turned Song-Hwa down when they were younger.

I loved the chemistry of the friendship between the main characters, on the other hand, and the cute side-bromance between Je-Hak and Jun-Wan. Despite being a support character, Je-Hak's storyline was one of the best, with a really satisfying ending.

Still, not sure why it's so highly rated, but I'm glad I watched it. I just wish the episodes were half the length. Who has time to watch 90+min episodes everyday?!
