I've personally seen freaky friday several times and I believe I also saw the original 70s vr as well, but I might be wrong xD
overall the concept is cute, kinda also like 18 again, it's like kids and parents are from different generations so they see things with a different eye but with these concepts both can finally look through the same view point and understand each other a little more

for me this is the only project from Jung So Min that I enjoyed, ironically it's when she's acting as a man xD that's why I say black listed actresses are bad becasue of type casting..

the plot was boring but I did laugh alot over the silliness of Yoon Je Moon acting as a girl and somin as the dad xD
I especially loved when she chased him and he ran away calling dad xD also yoon je moon dancing to sistar xD
