I hardly write reviews but I feel this drama is too underrated and doesn't do it justice. The stories that happened in the hospital and the characters are realistic and often touching and the acting of the 3 leads are fantastic. It reminds me of ER somewhat but it focuses on cardiology and 3 people, their growth, their change, their bond in the hospital. Story moves along much better than a lot of costume or profession cdramas or and it is perfectly cast. I dropped a lot before about firefighters, pilots, lawyers, businessmen because they are just not up to par or at all interesting but this one I think it's very well made and written.
