'Jirisan' Episode 16 Highlights: What Sparked Kim Sol's Revenge?
The season finale shows the details behind Kim Sol's vengeance against the former residents at the Black Bridge Village.
At an early age, he witnessed how his family suffered at the hands of their neighbors after his father resisted leaving the area.
First, a group of men killed her mother and claimed that she died because of an accident.
Second, his fellow villagers ruined their livelihood of beekeeping which caused his father to go insane and eventually kill himself.
The devastating incidents pushed Kim Sol to take his revenge, thinking they deserved to die in the mountains.
"Jirisan" episode 16 also continued Seo Yi Kang's confrontation with her prime suspect.
Initially, he denied the accusations but later hinted that he was the killer; unfortunately, the female ranger has no evidence to prove her claims.

She plans to catch Kim Sol on the act or collect information that would serve as evidence against him.
Unfortunately, the group's team leader, Park Il Hae and Jung Goo Young, lost Kim Sol after discovering the tracking device on his rucksack.
Despite the situation, Seo Yi Kang, with the help of their commander Jo Dae In, who was temporarily released in detention, checks the activities on the mountain using a drone.
Interestingly, she saw a blurry image of what looks like Kang Hyun Jo.
Together with the commander, they went to the summit through a helicopter and saw a signal from Hyun Jo, which points to the police headquarters.
