Chapter 16 End Of The Road
Sung-Chul speaking to Chul-Young in prison. This convict is excited about starting a new writing gig and vows to publish his book no matter what.
While he smirks, outside the prison Do-Ki pays his respects to his Mother. He's enraged, and Sung-Chul eventually catches up and tells Do-Ki he needs to finish what they've started. The whole team is there too, and they all show up to plan their next move.
None of them can forgive Chul-Young for what's happened and besides, they made a promise to Chul-Jin. They're going to see this through to its conclusion.
This begins with Hyun-Soo, whom Do-Ki heads up to visit. Sitting down to drink, he's shocked when he realizes Hyun-Soo doesn't seem to know anything about his Father. Realizing he has leverage over Chul-Young, Do-Ki visits him in prison and promises to gain revenge through Hyun-Soo. He is, of course, using the alias Dong-Chan. Do-Ki intends to reveal all. This is the one weak spot for Chul-Young, who drops to his knees and pleads for forgiveness.
Well, Do-Ki decides to keep everything a secret and not reveal the truth just yet, for Hyun-Soo's sake. While Chul-Young is en-route to being transferred, Sung-Chul receives a call that Han Mi-Ae, Chul-Young's wife, has passed away.
The catalyst for this heartbreak comes from Chul-Young sadistically breaking Hyun-Soo's arm outside the cell. He wasn't able to visit his dementia-riddled Mother in hospital and she fell down the stairs. He's obviously unaware of the link to his family until Sung-Chul reveals all. Chul-Young is crushed.
Meanwhile, Ha-Na makes her choice and decides against arresting Do-Ki. She tells him there's "not enough evidence" while an enraged Baek decides not to mention the secret prison. Ha-Ni likens him to a victim and although she's breaching her duties, claims it's worth it to help protect people. In fact, she decides against fighting anymore.
At the police station, Ha-Na hands in her letter of resignation. The Director knows about Rainbow Taxi though and rips up her letter, telling her not to run away like a coward and to catch 100 more criminals like Baek. In fact, the Director himself is going to resign. In his stead is the new deputy chief prosecutor, Do Joong-Won.
With the case resolved, all of our Rainbow Taxi members decide to part ways and go their separate ways. Kyung-Koo and a now-recovered Jin-Eon are going back to where they were before, while Go-Eun is going to take the civil service exam. Do-Ki is going to travel. Sung-Chul? Well, he's staying right where he is. He bows to them all and thanks them all for their hard work.
We then skip forward one year later. Chul-Young is brought in for trial while Chul-Jin is there too to witness this take place. Chul-Young stands up and admits the truth that he is the real killer. This allows justice to be served while Chul-Jin finally gets some retribution.
On the way out the courthouse, Sung-Chul learns the verdict to Baek's trial. The Goo twins have received life behind bars. Baek however, manages to get herself 20 years in jail – extended from 10.
So what of our other characters? Well, Do-Ki does indeed go traveling, pitching up a tent in a park and admiring the views. Jin-Eon winds up working at -what's assumed to be – NADA (The South Korean space agency) while Kyung-Koo works on a race course. Go-Eun passes her civil test and works as a police officer while Ha-Na appears to have been promoted at work.
Together, all the characters receive a ping on their pagers and convene at Sung-Chul's hideout once again. It turns out they're still working at Rainbow but now working to do this using both sides of the law.
