Amid the tension, Oh Soo Jae (Seo Hyun Jin) finds Gong Chan (Hwang In Yeop) as her source of happiness after she discovers more little things about him in "Why Her?" Episode 4.

On the other hand, the student apologizes to Oh Soo Jae for blaming her for Park Ji Young's (Park Ji Won) arrest.

'Why Her?' Episode 4: Oh Soo Jae Teams Up With Park Ji Young

In the ongoing case of Park So Young (Hong Ji Yoon), Oh Soo Jae teamed up with the victim's sister, Park Ji Young, to find more evidence and get new leads of the culprit behind the incident.

To make their plans work, the female lawyer faked Park Ji Young's arrest and promised to pay for her mother's hospital bills and monthly house rent. The lawyer explained to Ji Young that if she gets arrested, the authorities will have to re-investigate Park So Young's case, and if that happens, she can finally get justice for her sister.

Oh Soo Jae also found out that Park So Young was pregnant before she died and with a new source from Gong Chan, the victim requested for a paternity test of the child's biological father.

The lawyer reached out to Yoon Se Pil (Choi Young Joon) to know more about the Hansu Bio case. She then didn't know that she'll get proof from him about the ongoing case of Park So Young, that Chairman Han Sung Beom (Lee Kyoung Young) had an affair with the young lady.

Gong Chan Apologizes To Oh Soo Jae

Meanwhile, an additional video of Park So Young's last moments in the rooftop garden was retrieved by the legal clinic team, where a suspicious man was seen pushing Park So Young down. Oh Soo Jae then used it to request Park Ji Young's release from the prosecution.

After Ji Young's release, Gong Chan apologized to Oh Soo Jae, saying that he had misunderstood her. Interestingly, the professor unexpectedly mentioned the 7 billion dollar worth guy, which Gong Chan mistook as her boyfriend.

The law student was stunned to hear Oh Soo Jae's sudden explanation. Gong Chan then realized that his professor accidentally overheard his conversation with the restaurant owner the other night, which made him embarrassed.

On the other hand, Oh Soo Jae was on her way to her secret office when she found her door's lock broken. She dialled Gong Chan's number and told him where she was, and suddenly a suspicious guy appeared who planned to get the files involving the Hansu case.

Gong Chan, who heard that Soo Jae was in danger, immediately ran to help her.
