His royal hotness, Ji Chang Wook, comes off strong and effective Atty. No Ji Wook, as expected of his range as an actor. He has the ever familiar gestures and stares that he has used to charm his love interests, but it works. Maybe I have been charmed by his bright smile and finely chiseled face, but he is one of the most formidable actors in K-dramaland no doubt.
Support characters, Atty. Byun and Atty. Ji Eun-Hyuk, are also effective and lovable. Nara's Cha Yoo Jung leaves a remarkable performance, as well.
The female lead is a big disappointment, lacking maturity as an actress, and lacks more depth as a character; she is supposed to be a black belt in Judo(?) and quite a strong/tough woman and yet she comes off weak and easily shaken.
It is almost painful to watch her acting opposite Ji Chang Wook. Nam Ji-Hyun's take on the character Eun-Bonghee is quite poor. She uses the same character reference for the provincial girl she portrayed in Shopping King Louie; which worked then for that show. Sadly, the same portrayal for a different and more empowered character in Suspicious Partner is flat out failure. She acts all cute with a cutesy voice that is not typical of a supposed confident lawyer / (acquitted) murder-suspect / mature lady, which is disturbing. Could she possibly be a miscast?
Can the writer do something to make character Atty. Eun Bonghee, smarter and more confident please? She is clearly surrounded by danger and yet she goes out alone at night, etc? Gosh, please help this character, writer-nim!
