Cain and Abel Episodes I to almost III

I have started Korean TV drama Cain and Abel and so far into almost three episodes. I managed to fall asleep at the final minutes of the third episodes. Not because the drama is bad, I was just very tired and too stubborn to quit watching. So far we have two doctors who are almost brothers. One is the natural born son the other is adopted but loved very much by the father. Hopefully I'll write more in the upcoming days since Ramadan is starting on Friday and instead of sipping ice tea and having a smoke I'll be fasting :)
