Meh, overall average drama. Mannerisms of Park Eun Bin seemed like she was trying to relive extraordinary attorney woo days with jelloa do accent. ML was totally absent from whole drama and his brother (SML) seemed more prominent to the story, maybe he was overshadowed by his own younger self. One-time watch.
The whole struggle of FL seemed lacking with the addition of Kim Hyo Jin. Amidst the whole different storylines the writer should have given more time and emotions in each and every aspect of struggle from FL being above age, FL's struggle on Island(which should have been given a whole episode), Hyo Jin with her voice and ML with his family. Writer tried to tackle too much in too little detail and overall execution seemed bland and suffered from emotional disconnect. Finally the biggest weak point is in trying to lift up FL so much the casting of ML should have been better. He lacked so much screen presence in front of Eun Bin, guy should work in more dramas as Second lead or take more male centric parts to hone up his presence. I watched another of his drama Unlock my boss and it suffered from same problem.
Lastly, point of appreciation for high school parts played by teenage actors , they rocked their parts.
