Catching Up From Episode 3
The previous episode saw Park Hae Kang become an unlikely hero in his apartment complex after resolving a package delivery crisis, only to nearly lose the resident council election when he was framed for assaulting a neighbor. Once it came out that he’d actually been defending a security guard from an attack, his image flipped instantly — and he went on to win the election as building representative.

What’s Coming In Episode 4
The new episode opens by rewinding to Park Hae Kang’s past as the head of HK Trading and Investment, a front for a gambling operation run under his former gang, Oasis. While greeting a Japanese VIP at the den, he’s suddenly ambushed by yakuza members wielding weapons. Despite being unarmed, Hae Kang takes them all down with ease before calmly returning to shake the VIP’s hand, smiling as if nothing happened.
The show’s production team described the sequence as an intense, committed action scene, noting that the contrast between Hae Kang’s humorous election-campaign persona and his hidden past as a former mob boss is exactly what the flashback is designed to reveal.
Why This Flashback Matters
Dramas that blend comedy with a protagonist’s darker past often use this kind of tonal contrast deliberately, letting a single action sequence recontextualize everything the audience has seen so far — a narrative device tied to the broader tradition of the antihero in modern storytelling, as explained on Wikipedia. For Park Hae Kang, this brief but brutal glimpse into his past adds real stakes to a story that’s largely played out as a lighthearted political comedy so far.
