Been so long since I last watch Ji Sung and this drama is amazing! I thought it will be just like any other korean medical drama and I am pleasantly surprised with how good it is.

the casts did their job well and every episodes are amazing and filled with diseases and conditions so that you can also learn new knowledges. Dr Lee starts looking like an bnoxious guy but therought the drama you will see how kind and matured he is. I seriously think he is the key player in the Pain Department. He is clever and can also make everyone happy with just his presence. He is the kind of senior you wish to have at your workplace. He treats everyone fair without any bias. I'm not fond of Mi Rae since she seemed a little jealous at Shi Young in the first few episodes but you will see the real reason behind her attitude and she will redeem herself especially when she was with Dr Lee.

Ji Sung always acted as a peculiar characters and he is good! I'm hook in just a few second of his appearance. His character seem peculiar at first but you will understand his behavior later on. Yohan is such a great doctor even though almost all want him to fall and yet he still did what he love which is saving people. He had quite a sad childhood and that's what influence him to be a great doctor.

Those two nurses are cute! They are funny and always full with energy. The aunt is also a great character. She is always happy and positive especially when dealing with the annoying dr. Nurse Chae is really getting on my nerve and she is one twisted human. Her logic for hating Yohan is also weird. Prosecutor Son seem as an annoying person but he turned out to be a just person who always see everything with logic.
