This drama is superb. Very tight story and acting is superb. It won't be for those who doesn't like pure romance stories or those who likes fantastic events with their romance. It is very realistic mostly IMO and the pacing for me is just right (maybe except for the last 10 mins).

It is also something that you can't just take at face value. It shows 4 different couples and what their love looks like. And while others think that the other couples, I feel like they're necessary to what the writer wants to show (being true to love). Even the ending is great for me. We have 2 couples just starting their coupledom, 1 with pairing who knew each other so well and 1 who seems to have started it with rose colored glasses. And another 2 couples, 1 whi has been long married and who just got married.

I also liked that BoRa's book ended, not with the planned ending, but with her knowing she can recover even if she's just by herself.
