Ma-i nyoo pa-teu-neo (마이 뉴 파트너 / Mayi Nyu Pateuneo) (2008)

Young-joon, A Police Academy graduate, is a lieutenant working for the Internal Investigation Bureau; he is intelligent but very heartless as well. Now he's given the most fateful mission ever; to join an investigation team whose chief is Min-ho, his estranged father whom Young-joon hates more than anyone on earth. Min-ho is a completely diferent policeman, full of sentiment, and hunches. No doubt, they don't hit it off at all. How will they come up with a way to round up the gang as well as get over a long standing hatred, and misunderstanding as well?
