Han Joon Hwi Gets the Upper Hand Over Lee Man Ho

"Law School" episode 3 left with a cliffhanger deal between Han Joon Hwi (Kim Bum) and Lee Man Ho (Jo Jae Ryong.)

In the latest episode, the evening drama illustrates how the first-year law student toyed the convicted murderer in order to save professor Yang Jong Hoon (Kim Myung Min.)

He manipulated Lee Man Ho by pulling out reverse psychology and instructing him not to give his blood. Surprisingly, it was Han Joon Hwi who discovered that he is also an "Rh-O" type blood holder through a rare blood type cafe. With this, he managed to send a message, seeking for the said blood type.

Moreover, Han Joon Hwi predicted that Lee Man-ho would weigh himself with this. Since he gave the man instruction not to save professor Yang, this pushed Lee Min Ho to donate his blood, knowing that this would ruin Han Joon Hwi's plan.

He ended up saving the prosecutor turned professor, who is on the verge of his death after losing too much blood from a prison attack.

While on his recovery, professor Yang received the result from the second autopsy. Based on the findings, professor Seo Byeong Joo (Ahn Nae Sang) died from two possible causes. The first is through drug overdose, while the second conclusion is due to the hemorrhage caused by falling from the stairs.

With this, he also sued Prosecutor Jin Hyeong Woo (Park Hyuk Kwon) for publicizing details involving his alleged crime.

After being acquitted, all thanks to the second autopsy report, Professor Yang Jong Hoon returns to Hankuk University.

Upon his comeback, he gave the law students a new assignment relating to his case.

He asked the student to examine the murder case based on evidence and law. Moreover, professor Yang also questioned the class who was more suspicious among him and Han Joon Hwi.

Yang Jong Hoon Meets Lee Man Ho

At the Hankuk University hospital, professor Yang was approached by the convicted murderer.

There, Lee Man Ho revealed that it was him who donated the blood and the reason why he is still alive.

However, he remained unbothered by his revelation and mentioned that he must have had reasons why he saved him and tapped his shoulders as he left Lee Man Ho at the hospital's lobby.
