There is nothing more that can be said about this drama which has not been said already. So i can just start by showing my own dedication for this drama by opening an account just to review it after 2 yrs. You can tell about the quality of a drama if you cant find its replacement even after 2 yrs.
Now to start, The people who should avoid this drama? - Pre- teens / teens , those who still live in fantasy world!
Who should watch it? - Any Adult or mature person with enough life experience will truly appreciate this masterpiece.
What is the specialty of this drama? - Other than the usual like smooth & packed storyline, Great acting , OST etc
the real deal of this drama is how it captures greatness in simplicity. Now dont get me wrong I
appreciate all the supernatural dramas too but this is on another level its like watching Breaking Bad first time and not finding words to describe it. In this show you'll see what walking with a heavy heart feels, what it really means to have a warm heart, what integrity looks like, what being a family really means , what guilt actually feels like, what to Love sby really means!(Not the lead), what renunciation really means, the joy of companionship, and last but not the least how to show immense Love, Respect and admiration without WORDS!

Any special character? - Other than the leads (3 bros and The girl), there are 4 special characters - 1.The lady shop owner, 2. The cleaner , 3. The grandmother, 4. the Monk. You'll know why they are special when you watch the show.

Any drawbacks? - The only drawback I can think of is a character related to the youngest brother that character should not have been given that amount of screen time, and That's why I am not giving it 10\10.
