Yes, this word describes this drama perfectly.
Firstly, I would like to ask if you've watched this writer's drama before?
If yes, you know how it's gonna be like which is just awesome.

If not, give this a try.
Also, the fact that this is a low budget drama, nothing fancy, it sticks to the basic script provided and the direction is good enough.

But More than half of the screenplay in this drama for the side family characters was a hassle, I skipped it.
But what kept me watching this was the quad couple.
This has to be one of the most fascinating drama's I've watched.
Brilliant chemistry, authentic dialogues, sensible and impeccable conversations.
You rarely come across all these.

As for the word entangled, this drama has every character entangled to each other, and as the episodes progress the web keeps on solving itself.
You realize how the characters you disliked initially had a pov that mattered.

Everything has a reason and subtle, honest conversations can have a calming effect on everything.
Issues can be resolved.
It's a lovely drama to have come across and be watched.

Also, this is the first drama where the 2nd couple almost threw away, more like overrode the 1st couple.
Their characterization and chemistry was damn brilliant.

Overall a must watch drama if you've patience and you love to learn the real progression.
Could it have been better? Yes certainly!
Is it the best out there? Nope.
But does it do its job? Yes, pretty much.
But that's the feeling you get with every drama .

Special mention to Park Hyung Shik, the guy has the talent to be a mega star.
Especially after watching his performance on Suits.
He literally stole the lime light from everybody in this drama , even Uee and Sung Joon.
