I think there was a very interesting main story, but also others.
I thought the acting was great.
I also think it's good that the mother hasn't abandoned the son from her best friend or father over the years, just because the father was mad at her and blamed her for the death of his wife.
I thought the ending was great because he was also able to live out his dream in Switzerland and she was waiting for him.
I just loved watching every episode and think I could watch it again.
you should really give the drama a chance
