“We can’t trust the main character”. Who will be the real Big Mouse?
All the characters in the drama are suspicious, from Jerry (Kwak Dong-yeon), who follows and helps Park Chang-ho (Lee Jong-seok) the most in the prison, to Park Yoon-gap (Jung Jae-sung), the prison director and the most powerful person in Gucheon Prison, and even Noh Park (Yang Hyung-wook), who is favored by the prison director.
Park Chang-ho, the main character who is falsely accused and involved in a battle of blood, sweat and tears, is no exception. Even Chang-ho’s wife Ko Mi-ho (Lim Yoon-ah), Ko Mi-ho’s father Ko Gi-kwang (Lee Ki-young), and Chang-ho’s best friend – lawyer Kim Soon-tae (Oh Eui-shik) are suspected by the viewers.
Meanwhile, in episodes 9 and 10 of “Big Mouth”, which aired on August 26th and 27th, the prison director was revealed to be a subordinate of Big Mouse. Jerry, who used to be the most suspicious figure, seems to have been free from suspicions after getting seriously injured in a mysterious accident while trying to save Park Chang-ho. However, as Jerry was seen checking and tearing Chang-ho’s note when he returned, the viewers raised doubts again.
The secret of Mayor Choi Do-ha (Kim Joo-heon), who was thought to be helping Chang-ho, was also revealed. Choi Do-ha, who made Chang-ho be involved in the murder case, was an accomplice in the murder case of Professor Seo Jae-yong (Park Hoon). In addition, he also shocked the old man (Jeon Kuk-hwan) by revealing his spiteful past story.
Many people are reasoning to find Big Mouse by looking for hidden clues together with the main character Park Chang-ho. The fact that Park Chang-ho is also 100% unreliable increases the viewers’ immersion in “Big Mouth”.
There are still many stories to unravel regarding why Big Mouse is so obsessed with Seo Jae-yong’s thesis and the connections between Gucheon Prison and Gucheon Hospital. The mystery game called “Big Mouth” is expected to continue with many plot twists.
