it's very original, heartwarming, uplifting, discusses also Alzheimer's and how the affected (grandpa) hides it from his family trying to cope with it on his own by writing verything down; how a stranger Chaeroki deals with it and then informs the son who is a doctor and then the rest family not knowing that Haenama, the grandma, has overheard the chat and decides to wait for the husband to tell her not wanting to hurt his pride, confidence and not stand in the way of his dream. How both respect, love and have each other's back after 50 years being married, not taking each other for granted which is the secret of a good marriage in my opinion; how the family rallies round their dad/grandpa; how teacher and pupil (Chaeroki/grandpa, Chaeroki/his ballet teacher, C's coach dad/Hi Beom), the latter and his ex-wife who remarry, C and is dad how they all learn from each other to respect and to ask for forgiveness. It is just a beautiful series: thank you writer, actors, actresses, producer, Netflix. It's an understated and undervalued series (noticed that in Korea ratings were 2.5%, maybe that's why it's not 16 ep. Ep 11 is def. my favourite. There is nothing I do not like! xxx
