I watched the movie, but as usual, the Koreans made it into a drama and nailed it. ML was going through a mid-life crisis and became young. This drama is so funny at some point, plus ML was so confused sometimes because he didn't know things about today's teenagers. I can't recall if there was anything bad in this drama because, at the end, everything was fixed. FL was great too; she handled herself pretty well even in difficult moments. The best couple were actually the side couple, because they stole the show whenever they were on screen. Pretty great watch at the end. I am losing words because I can't define it's greatness.
