'How to Become a Building Owner in Korea' kept viewers on edge with one escalating incident after another. High-profile stars Ha Jung-woo, Im Soo-jung, Jung Soo-jung and Shim Eun-kyung generated strong buzz before the show premiered, but the latest episode, which aired on the 28th, slipped to a series low of 2.6% in ratings.

In the fifth episode of tvN’s weekend drama How to Become a Building Owner in Korea (hereafter Building Owner), which aired March 28, an unexpected incident in an underground cold-storage room upended Gi Su-jong (Ha Jung-woo) and Kim Seon’s (Im Soo-jung) plan to deal with an accident involving Oh Dong-gi (Hyun Bong-sik).

Gi Su-jong and Kim Seon had Oh Dong-gi locked in the cold storage and argued over how to handle him. Gi was rattled—he hadn’t expected Oh to be stabbed. Kim, a former nurse, stayed calm, treating Oh and cleaning the scene. Gi found comfort in his wife’s composure, but he was suddenly consumed by anger when a memory of her affair with his friend Min Hwal-seong (Kim Jun-han) surfaced.

Kim urged him to focus on the immediate crisis, saying, “We both made mistakes—let’s deal with what’s urgent first.” She steadied him with: “We have to try. You have to choose—your family, or this person (Oh Dong-gi).”

Gi apologized to Oh and attempted to negotiate. Though he briefly entertained extreme options, he couldn’t bring himself to harm him. Oh, who knew that the money Gi had hidden in the bathroom came from the kidnapping, demanded 1 billion KRW (approximately $750,000) to keep quiet. He shouted, “Are you going to kill me? You’re not that kind of person—think of your daughter,” trying to sway Gi, who is a father.

Eventually, Gi and Kim coerced Oh into participating in a staged video in which they all swore to keep the secret. The plan was to frame Oh as a co-conspirator in the kidnapping and silence him. Oh agreed to be released in exchange for the payoff, but when he heard someone nearby he broke the agreement and tried to escape. A struggle with Gi left Oh with a fractured finger.

Oh’s rage and desire for revenge triggered a larger, unforeseen consequence. Near the episode’s end, Jeon Yang-ja (Kim Geum-soon) sneaked into the Seyun Building to cut pipes and sabotage it. In the dark, Oh mistook her for Gi and attacked. The episode closed on Jeon bleeding in the cold storage while Oh fled—leaving viewers to wonder how the fallout will hit Gi and Kim.

The ambitions circling the Seyun Building created a spiral of incidents. Gi had joined a fake kidnapping to protect the property, then imprisoned Oh to cover it up—choices that culminated in Oh attacking Jeon Yang-ja. Jeon herself had targeted the Seyun Building to secure redevelopment shares and was injured in the process. Each character’s greed set off consequences that may be irreversible.

Gi expressed regret for taking part in the staged kidnapping, but felt compelled to clean up the mess for his family. Kim vowed, “Let’s go through this together,” putting the couple’s fate at the center of the story. Meanwhile, Jeon Yi-kyung (Jung Soo-jung) discovers her husband Min Hwal-seong’s affair and finds a photo showing Kim Seon’s back on his phone. A flashback to her own kidnapping hints at further upheaval in episode 6, raising anticipation for what’s next.
