Family is No. 1" (High Kick) broadcast from September 2009 to March 2010 was the most popular sitcom drama in Korea, with a rating of up to 24.9%.
However, the ending of "Family is Number 1" part 2 in 2010 is still controversial to this day.
In which, the character doctor Ji Hoon (played by Choi Daniel) and the maid Se Kyung (played by Shin Se Kyung) suddenly had an accident and died together.
This ending caused outrage for a long time, because "Family is Number 1" was originally a movie with a cheerful, humorous color throughout, but the ending of this couple was sad, fleeting, even considered "unreasonable".

Recently, actress Shin Se Kyung appeared on Jung Jae Hyung's talk show and shared about the ending of "Family is Number 1" part 2 after 16 years.
MC Jung Jae Hyung said: "At that time, it really caused a lot of noise, right? Looking back now, it was just a sitcom, but at that time it almost became a big social problem.
Shin Se Kyung sighed and replied: "Until now it's still noisy. I still regularly hear about it. It can be said that this is one of the most mentioned endings in history and that work has never been missed when people talk about controversial endings.
The actress recalled: "The last episode was also the day the film crew held a wrap-up party. We all gathered together to watch together.
There were also many reporters at that time. But I remember that before knowing what was happening, the atmosphere was very unusual. It felt like something very big was happening outside the room we were sitting in.
Jung Jae Hyung added: "The external reaction is really intense. Watching it again, I see how much the movie is loved.
Shin Se Kyung also agreed, saying that the controversy that has lasted until today is proof of how deeply the audience has been attached to the characters and the story.

However, the actress emphasized that mentioning the movie is still a topic that needs to be very careful, she said: "When mentioning "Family is number 1", you have to choose your words very carefully, especially about the ending. That was the first time I really felt the power of public love for a work that was so great.
However, Shin Se Kyung's sharing reminded the audience of information revealed by Korean media that she was the one who came up with the idea of a sad ending for "Family is Number 1". Because of this, Shin Se Kyung was questioned and criticized by many movie lovers.
Many years later, director Kim Byeong Wook said that the ending did not change just because of an idea of Shin Se Kyung, which was discussed a lot between the director, screenwriter and production team.
The ending of the film was only decided to be sad a few days before the final episode aired, while actress Shin Se Kyung's proposal was from a few months ago, so it is not possible to blame the actress alone.
