"Taxi Driver" Episode 4 Recap

The drama continues with LeJee Hoon's character, Kim Do Gi, who deals with three high school bullies.

In the previous episode, he surprised the viewers with his transformation as a geeky substitute teacher in hopes of avenging the helpless Park Jung Min (Park Joon Mok).

To recall, he was brutally victimized by the group led by Park Seung Tae (Choi Hyun Wook), alongside his two sidekicks Jang Hyung Sik (Lee Jae Hak) and Oh Hak-Soo (Lee Min Jae).

"Taxi Driver" episode 4 featured how the students attempt to terrorize their new teacher by framing him up in a sexual harassment incident.

Interestingly, Kim Do Gi managed to get the upper hand with the help of his Rainbow Taxi teammate, Go Eun (Pyo Ye Jin), who disguised herself as a schoolgirl.

At this time, the group is still clueless that the taxi driver turned teacher is starting the revenge.

Kim Go Gi Gets the Leverage over the School Bullies

"Taxi Driver" episode 4 also showed how Kim Do Gi gets the leverage over Park Seung Tae's group.

In one scene, the school bullies tried to harass an elderly man by persuading him to buy them a pack of cigarettes. However, it turns out that the old man is selling the same thing. Little did they know that it was marijuana and not a cigarette.

The next day, they find the old man was arrested by two Rainbow Taxi members, posed as a police officer. Right then and there, they learned that it was marijuana that caused them to run into the woods and hide their stash.

This is where the fun starts for Kim Do Gi. During their class, the teacher purposely played a video of the incident where the group is burying the marijuana packs, hinting that he knew about the boys' dirty little deed.

He sarcastically mentioned not reporting it to the police, and it will be their little secret.

The next scene featured Kim Do Gi telling the group to loan him five million won in exchange for his silence. Although Park Seung Tae initially refused, he caved into his demands and said that he'd only give the money at his chosen time and place. This also gave him the chance to call his hired uncle for backup.
