This is the 1st time I write a review about a K-drama, this series is not my type of drama as I love Rom-Com types the most, but to be honest this is the deepest K-drama I have ever seen, the writer really did a great Job, this series involves all kind of relationships that you can imagine, and they are really deep, connected and sincere and the script and the dialogue can't be better than this, the director and the actors really did an amazing job as all the main characters whose are so many shined brightly and made me feel a unique feeling I didn't experienced before, so even so this is not my type of drama, I was really touched by the story and it's development until the final episode, I didn't feel that I wasted anytime, and I would never regret watching this drama, whatever your drama preference when you see this gem, you won't be disappointed, I forgot to say that I cried a lot while watching many scenes without spoiling any of them but these scenes really touched my soul and made me feel better, finally about the rewatch value I would never watch this series again as I believe it's a one-time watch for the lifetime from my humble opinion
