Netflix’s Bloodhounds Season 2 spent 16 consecutive days at #1 in Korea after its release, and the buzz went well beyond domestic borders. Within three days of launch, it hit the Top 10 in 92 countries, taking the #1 spot in 16 of them.
A big part of that success is coming from an unexpected place: singer-actor Rain (Jung Ji-hoon) delivering his first-ever villain role to widespread acclaim. Here’s the plot, the cast, and everything foreign viewers should know before diving in.
What Is Bloodhounds?
Bloodhounds is a Netflix original Korean series based on a webtoon of the same name. Season 1 premiered on June 9, 2023, and Season 2 dropped on April 3, 2026. Both seasons were directed by Kim Joo-hwan.
Season 1 was an action noir built around illegal loan sharking. Two young men skilled with their fists, Kim Geon-woo and Hong Woo-jin, team up with a retired loan-shark legend, Choi Sajang, to take down a ruthless illegal lender who operates above the law.
Season 2 picks up roughly three years later, and the world expands significantly. Instead of loan sharking, the story shifts into illegal gambling, underground boxing, and the dark web — while keeping the original’s core theme that money is at the root of every crime.
Season 2 is an original story that goes beyond where the source webtoon left off.
Season 2 Plot (No Spoilers)
The story kicks off when Geon-woo becomes the target of a global gambling operation running an illegal boxing league. When the criminal network threatens the people he cares about, he teams up with his best friend Woo-jin once again for a final showdown.
Where Season 1 stayed within Korea’s loan-sharking world, Season 2 goes global with its underground boxing league setting.
As Geon-woo rises toward the top of this brutal world, he draws the attention of Baekjeong — a massive new threat — and the fight to protect his loved ones becomes the heart of the season.
Cast & Character Relationships
Kim Geon-woo (Woo Do-hwan)
The lead, returning from Season 1. His fighting skills are unmatched, and in Season 2 he finds himself up against the underground boxing world’s most dangerous threat.
Hong Woo-jin (Lee Sang-yi)
Geon-woo’s best friend and partner. They fought loan sharks together in Season 1, and in Season 2, they face this new threat side by side once again.
Baekjeong (Rain / Jung Ji-hoon)
The season’s main villain. He brings a commanding, menacing presence that raises the tension throughout the show.
Rain has said filming was physically and emotionally exhausting but genuinely made him happy, and he’s expressed interest in returning if a Season 3 happens — saying he’d want to see the story through to the end.
Choi Sajang (Heo Joon-ho, Season 1)
A retired legend of the loan-sharking world in Season 1, who helps Geon-woo and Woo-jin. Key to understanding the emotional foundation of the franchise if you start from Season 1.

“Can I watch Season 2 without seeing Season 1?” Since Season 2 is set three years later and shifts from loan sharking to underground boxing, the main plot works reasonably well on its own.
That said, if you want to actually feel the weight of Geon-woo and Woo-jin’s friendship — and their bond with Choi Sajang — starting with Season 1 is worth it.
“What exactly is Korean ‘loan sharking’ (사채업)?” In Korea, this refers to unofficial, unregulated lending at extremely high interest rates, typically targeting people who can’t get approved for a bank loan.
Season 1 leans into the violence and illegality of this world — and it hits harder because it’s based on a real, recurring problem in Korean society.
“Was Rain always an actor, or is he better known as a singer?” Rain first became a household name in Korea in the 2000s as a solo male pop star, and later expanded into acting over the years.
This is actually his first true villain role, which is part of why the casting and his performance became such a big talking point in Korea.
“Why is the rating so high (19+)?” The action is intense, and there’s a significant amount of graphic violence throughout. Season 2 in particular has been noted as even more brutal than Season 1 — worth keeping in mind before you start watching.
By the Numbers
According to Netflix’s official ranking site, Tudum, Season 2 racked up 7.4 million views in its second week alone, landing it at #1 on the Global Top 10 Non-English TV chart.
It reached the Top 10 in roughly 80 countries — including Korea, France, Brazil, and Vietnam — and held the #1 spot in Korea for 16 straight days after release.
Quick Checklist
- Start with Season 1 if you want the full emotional payoff
- Check the 19+ rating before diving in — this one’s violent
- Don’t miss Rain’s villain performance — it’s the season’s biggest talking point
- No official word yet on Season 3 — we’ll update this once there’s news
Final Thoughts
The setting shifted from loan sharks to an underground boxing league, but the bromance between Geon-woo and Woo-jin — and the sheer intensity of the action — carried straight through.
Add Rain’s surprise turn as the villain, and Bloodhounds Season 2 became one of the standout Netflix K-dramas of the spring. We’ll update this post as soon as there’s official word on Season 3.
