This show has great characters, more complex than they first look. There's also a nice balance between funny moments and some moments that are meaningful (and a little sad let's be honest). I'm a sucker for revenge stories so there's also that.
There's a bit of a pace problem towards the end, I'll admit it, but I really enjoyed the writing of the characters so it kept me going.
If you're looking for a love story with kisses and hugs, maybe this won't work for you because the main couple is very proud and dignified and they're also very different people with different aspirations and goals... But the chemistry was real and the longing gave all the feelings.
And there is indeed a lot of love in this drama, and a lot of values. It deals with honor, grief, frienship, the promises and obsessions we can't let go of...
I recommend giving it a go, I rewatched it recently and I'm still very fond of how well each character is written.
