This would have been great as a 16-20 episodes drama and more polish. The formula/concept didn't work for a 120(60) episodes drama. The first 15-20 episodes were really boring slice of life bits scattered, it does get a little bit better once they become "parenting daddy". The drama also lacked proper tension to keep the viewers engaged. Some very distracting poor performance by Oh Jung Yeon, her facial muscles were completely dead. This drama was her only main acting role for a reason. She also works as an announcer and TV presenter, I can see that working for how stiff she looks. There was an attempt but I expected a lot more from the drama, just like your kids.
