I waited all the episodes to finish and downloaded them so that I can binge-watch (and re-watch) over the holidays. It was worth all the wait.

Story
Beautifully written story with almost no holes in it. The relationships between parents and children, husbands and wives, siblings, colleagues, friends, in-laws, are all shown realistically. I like family drama (NOT revenge theme though) and the storyline here is similar to other family dramas. What is different in this drama is that it is not all about sacrifice. I sometimes get frustrated with sacrifices in dramas. It has some sacrifice but not the main theme. It is about how individuals give their life another chance and live their life once again with support from family and friends. There is no extra storylines in here. Every characters has their own story and each story is necessary to create "Once Again".

Acting/Casting
I can't image the characters played by other actors/actresses. They all fits in really well. I have seen Mr. Chun Ho Jin in "Seo Yeong, My Daughter" and "My Golden Life". He can be a 'loser father', 'forgiving father', or 'frugal father'. The chemistry between the couples is amazing. (COUPLES here include all the couples you could pair in the drama . Lee Sang Yeob and Lee Min Jung are already my favorites (they are one of the reasons I watch this show). And I found two people I need to start rooting for "Lee Cho Hee and Lee Sang yi" . For 'Oh Yoon Ah' and 'Oh Dae Hwan', I have seen them playing vallians, but here they are cutest and most understanding oppa and eonnie to their younger siblings, and best most hard-working appa and eomma to their children.

Music
Music was okay ... I am not a music expert.
Am I going to re-watch this show? YES, I will ... I downloaded so I could re-watch anytime.

Warning ...
If you are a crybaby, watch it on the weekends ... so that you don't go to school or work with puffy eyes. Every episodes will make you cry, laugh out loud, smile ....
