The storyline is quite unique.
The emotional rollercoaster is enjoyable.
I've watched it 3 times.
It's a mixture of comedy, love, suspense, thriller, sadness, happiness.
The bonds are spacial. Now days drama are mostly focused on NC scenes and mess up the storyline and plot actually they don't care about it.
But it doesn't mess up things, it's a perfect mixture.
Over all I love it.
