Choi Tae-joon was the reason Nara and Ji Chang-wook broke up.
The ninth and tenth episodes of the SBS drama "Suspicious Partner" showed why Noh Ji-wook (Ji Chang-wook) and Cha Yoo-jeong (Nara) broke up.
Noh Ji-wook ignored his ex-lover Cha Yoo-jeong and Eun Bong-hee (Nam Ji-hyeon) pretended to be his girlfriend. Noh Ji-wook told Eun Bong-hee, "I went to her house one day and I saw her with someone else. That's all".
Noh Ji-wook quit the law firm and decided to set up an office to work with Eun Bong-hee with. Ji Eun-hyeok (Choi Tae-joon) asked him to put him on his team but Noh Ji-wook ignored him. Ji Eun-hyeok then said, "I want to tell you what happened that day".
