Jeon Do-yeon and Park Hae-soo lead tvN’s The Great Bang Ok-sook

# What the show is about

Ok-sook (working title) adapts a webtoon about a conflict between two organized groups centered on housing and redevelopment. At the heart is Bang Ok-sook, a longtime resident who finally owns an apartment with a Han River view and makes protecting that property value her top priority. When nearby redevelopment sends neighborhood prices downward, she leads the Noble Gold Castle Women's Association to resist the change.

Opposing her is Yoon Tae-woong, the redevelopment association president. He's described as a calm, effective operator — called a "gentle gangster" — and he has a history of turning stalled redevelopment plans into completed projects. His arrival fast-tracks a decade-old redevelopment effort, which directly threatens Ok-sook's community.

# Who's in the cast

• Jeon Do-yeon as Bang Ok-sook, the association's leader and the central figure of the anti-redevelopment movement. She's portrayed as tough, pragmatic, and invested in maintaining her apartment's market value after years of hardship.
• Park Hae-soo as Yoon Tae-woong, the redevelopment chairman with a 100% success rate in getting projects moving.

Supporting cast members who join Ok-sook and the Noble Gold Castle Women's Association:

• Kim Sun-young as Lee Ho-young, a rival within the association.
• Kim Geum-soon as Yoon Ji-ae, the association's president.
• Kim Guk-hee as Oh Ji-hee, who bills herself as the group's "minus hand" when it comes to investments.
• Woo Jung-won as Do Do-hee, outwardly standoffish but caring.
• Gong Sung-ha as Kim Ye-ri, a social media influencer.
• Baek Hyun-jin plays Ho-young's husband and helps the association in his role as a journalist.

# Creative team and schedule

The series is directed by Kim Hyung-shik, known for Under the Queen's Umbrella. The screenplay is by Lee Gi-cheol, credited for work including Alienoid: Part 2. tvN has set the drama to air in the first half of 2027.

# The central conflict

# Why the casting matters

Jeon Do-yeon and Park Hae-soo are both established actors with strong track records in dramatic roles. Their casting positions the series to explore both the emotional stakes of homeowners and the procedural side of redevelopment efforts. The supporting ensemble adds a range of perspectives within the residents' association, including rivals, pragmatic leaders, and a media-connected ally, which suggests the show will mix personal drama with community-level strategy.

# What to expect next

Promotional materials, episode details, and a firm premiere date should follow as production progresses toward the scheduled 2027 broadcast window. The series' webtoon origin and ensemble setup indicate a story built on community dynamics and conflict over urban development choices.
