Ojakgyo Brothers is the 3rd best Family drama out there in my opinion. It's exceptionally well written and you fall in love with all the characters.
they are different but yet somehow certain things give you the same "feelings" as you're watching the drama - MDSY is definitely Unique and I don't think it could be "fully" compared to another drama. but there are "little" similarities in certain things - not a lot mind you - but if you liked MDSY - you should be the type that would like this drama too.
