For me, this is like almost impossible to list cuz I have seen almost every drama I rated 7 and above on my list at least twice... So, but most watched for me would be coffee prince, city hunter, kings 2 hearts, faith, all the gokusens, mars, both bloody Mondays, Kimi in todoke, ma boy. Gosh they re just to much to count and I lost count of how many times I ve seen the ones above...
