I literally binge-watched this drama in 2 days.
It was that enjoyable until I got to episode 14. All the reviews and comments I'd read before I began watching it did not prepare me for the last three episodes. If Jun was going to come back, why have his mum lie about his death and keep lying to everyone for five years? What if Ra-Ra had married someone else? Who lies about their death like that or their son's death? Only to resurface after 5 years and expect to carry on from where they left off? Utter nonsense!
I cannot believe the ending... did not make sense AT ALL!!! I wish I knew what the writer and director were trying to prove.

Rant over, I loved the actors and their acting, the characters and the story up until episode 13.
I didn't like Go Ara in Hwarang (the only drama of hers I'd seen prior) but she totally nailed this role.
Lee Jaewook was amazing as always. It's so hard to believe that he is so young!
Everyone else did a good job.

The piano pieces were lovely, a bit too long in parts but they were a lovely addition.

Skipped over some of the other side characters' parts but it didn't take away from the drama.

I probably would not watch the whole drama again, but would definitely watch certain parts of it.
