'Big Mouth' Ending Explained: How did Miho get cancer? Is there season 2 of K-drama?
SEOUL, SOUTH KOREA: 'Big Mouth' has come to an end with its highest viewership rating for the finale at 13.7% nationwide. It was also the most-watched K-drama of its time slot and the most-talked about K-drama for the last few months. Actor Lee Jong-suk continues with his winning streak of picking up successful projects while Girls' Generation's Yoona was applauded for her role as Miho. Well, episode 16 which was the finale answered a lot of questions like how did Miho get cancer and also left fans asking -- is there season 2?
Well, the ending was explained and also kept open-ended for the possibility of season 2 if the 'Big Mouth' producers got the green light. The finale opened with the election debate where Jong-suk's Changho is being sabotaged. In the meantime, Miho goes to the fish farm. She tricks the manager into thinking he has drunk the water she was exposed to and finds out that the wastewater of NK Chemical is used at the fish farm.
'Big Mouth' finale tells how Miho got cancer
As we reach the 'Big Mouth' ending, Soontae asks Miho's father about her mission and the viewers find out why no one wondered if Miho had cancer -- because they thought she was exposed to groundwater and not the fish farm's wastewater when she followed the model inmates. Turns out a large dose of radiation was discharged while refining NF9, a miracle drug to the ocean via the fish farm for the last 30 years.
At the debate, Choi Doha continues to sabotage Changho as he gets the cryptocurrency scam artist on the questioning panel. Soontae also pulls strings and gets Miho on the panel where she reveals she got cancer due to illegal waste dumping. She also plays the video of the manager exposing the fish farm.
Choi Doha is not punished
Protests erupt to get Choi Doha to withdraw from the election. He is being investigated but there is not enough evidence. This leads to Changho setting up a trap for Juhee. He tells her about their plan to prove Elder Kang's murder which triggers her. She tells Doha's driver that she already knew her husband killed Kang. On the other hand, Doha is not arrested and says he'll look into his company NK Chemicals to appease the victims.
Changho's team is sure they are ahead in the election as they exposed Doha's corruption. But Doha wins and is reelected as mayor. Juhee feels guilty and gives his burner phone to Changho. She also agrees to testify against him. But Doha catches her through a spycam and she is sent to the mental asylum. Doha is found not guilty. Miho faints while voicing her frustrations and is hospitalized. She and Changho assure each other of their love with Miho dying in her sleep.
Changho takes drastic measure
With nothing to lose, Changho confronts Doha at the pool where the mayor doesn't show remorse. Changho then reveals that he won't feel bad as he has added the radiation wastewater to the pool Doha swam in. A shocked Doha coughs blood and falls into the water.
NK Chemicals is sued. The gold Doha stole from Big Mouse and Seo Jaeyoung's paper is found. Juhee is rescued and testifies that his paper indeed links the NF9 development process to the growing cancer rate in Gucheon. The VIPs are jailed for 10 years for his murder. Big Mouse's team donates the gold to orphanages.
Is there season 2
The K-drama ends with Changho visiting Miho's grave and remembering her words of wanting him to be a good Big Mouse who helps the poor. It looks like he is reconsidering giving up Big Mouse's position as he'd earlier said he would. With Doha's dead body not being shown and Kang's serial killer son also being alerted of his father's death but not making an appearance, viewers wondered if there would be a season 2.
Well, on September 18, the 'Big Mouth' producers shared, "We think it's too soon to be discussing season 2. We'll work hard to try and return with a good project." With several K-dramas getting a season 2 like 'Yumi's Cells' and 'Alchemy of Souls', the possibility of sequels in the K-drama industry is now not too far-fetched.
